Abstract:

Albinism in birds is a unique phenomenon therefore it has been recorded in several species by various others (Avizanda et al 2010, Dudgeon, 1904; Gurusami, 1992; Inglis,1903; Javed, 1992; Mahabal, 1993; Prasad, 2000; Pande et al2005; Pawashe et al 2006; and Sathiyaselvam, 2003;Gupte 1969;Sharma 2003). According to geneticists Hutt and Mueller in 1941, defined four major degrees of albinism, 1). Total albinism: the rarest form, in which all the morphology of birds white with pink eyes, 2). Incomplete albinism: in this condition melanin pigment completely absent from (birds) feathers, skin, or eyes, but not from all three. 3). Imperfect albinism: in which melanin pigment only partially inhibited, creating a pale organism. 4). Partial albinism, the most common form, in this condition localized body parts are white or whitish and their legs, and bill are common as other Jungle babblers (Turdoides striata).  The majority of white birds are found in this fourth category. Albinism is a condition when the amount of melanin pigments reduces from the body.

Abstract:

Albinism is a clinically and genetically heterogeneous group of hereditary diseases whose pathogenesis is mediated by impaired synthesis of melanin which results in its partial or total loss. Reduced melatonin level clinically manifests as skin, hair, and ocular hypopigmentation. Ocular presentations include hypopigmentation/lack of pigmentation of eye fundus and iris, foveal hypoplasia, low vision, nystagmus and strabismus, photophobia, iris transillumination, and asymmetrical decussation of nerve fibers at the optic chiasm. However, albinism can be a part of more complex genetic syndromes, e.g., Hermansky-Pudlak syndrome or Chediak-Higashi syndrome. These disorders should be identified as early as possible to start therapy to prevent life-threatening conditions. Partial albinism with ocular, skin or hair hypopigmentation not associated with melanogenesis (e.g., Griscelli syndrome, Waardenburg syndrome, Aland Island eye disease, etc.) also occurs. Each case of albinism requires an accurate molecular genetic diagnosis to provide a personalized treatment approach, predict life expectancy and health status, and plan pregnancy. Keywords: albinism, Hermansky-Pudlak syndrome, Chediak-Higashi syndrome, hypopigmentation, clinical polymorphism, genetic heterogeneity.

Abstract:

Two cases of albinism in roe deer were reported in the Lublin region in the spring of 2017. Both animals were females. One of them was a mature female roe deer with partial albinism. The other was a young roe deer (kid) born in the previous hunting season, which was a true albino, most probably descended from a female roe deer with pseudo-leukoderma. Since the eyes of these animals could not be examined, it was impossible to conclude about their leucism. No male roe deer in a group of 14 animals showed phenotypic features of albinism. This confirms that albinism in roe deer occurs very rarely, because it is conditioned by recessive alleles, and its phenotypic manifestations can take many forms..

Abstract:

Albinism is a genetic disorder in which there is a defect in melanin production, a pigment which gives color to the skin, hair and eyes. This congenital malformation can also occur in sea turtles, although it is not fatal, but it reduces their chances of survival in the natural environment. Even so, there are still no reports of its occurrence in Eretmochelys imbricata, a species known as the hawksbill turtle or legitimate turtle, with wide distribution in tropical seas. The present study describes the case of an individual with partial albinism in the E. imbricata species, found on the northern coast of Rio Grande do Norte, Brazil. The animals were collected at Cabo de São Roque beach in January 2020 during the reproductive season of the species. After analyzing the animal, it can be classified as having partial piebald albinism, since it still has lighter spots both on the skin and in the carapace and plastron regions.

Abstract:

Albinism in plants is characterized by partial or complete loss of chlorophyll pigments and incomplete differentiation of chloroplast membranes. This is a very common problem encountered in interspecific crosses and tissue culture experiments including anther culture and generation of doubled haploids. This impairs photosynthesis and the plants eventually die at a young stage without reaching maturity. Environmental conditions such as light, temperature, media composition and culture conditions may key factors in determining the frequency of albino plant formation. This short communication reports the first instance of albinism recorded in Prinsepia utilis Royle. An albino seedling was observed during the standardization of nursery techniques.

Abstract:

Albinism is an uncommon phenomenon and inherited condition in animals characterized by a partial or complete lack of melanin. The family Xenodermidae Gray, 1849, is a group of caenophidian snakes widely distributed in South, East, and Southeast Asia, including five recognized genera and 36 species. However, there are currently no reports of albinism in any species in Xenodermidae. Achalinus sheni Ma, Xu, Qi, Wang, Tang, Huang & Jiang, 2023 was first described based on five male specimens from Loudi City and Nanyue District, Hunan Province, China. At the time, there were no descriptions on female individuals. In this study, we report in detail a collected albinistic specimen of A. sheni, which is the first discovery of wild albinism in the family Xenodermidae. We also provide photographs and descriptions of the first three female specimens of A. sheni and extend the diagnosis of this species.

Abstract:

(Uploaded by Plazi for the Bat Literature Project) During the last 60 years, 34 cases of aberrant colouration in bats of the following species have been recorded in Poland: Rhinolophus hipposideros, Myotis daubentonii, Myotis mystacinus, Myotis nattereri, Myotis myotis, Eptesicus serotinus, Barbastella barbastellus and Plecotus auritus. The largest number of aberrant colouration cases was recorded during the hibernation period in the Nietoperek bat reserve, western Poland (0.016% individuals with albinism). In 2014, five individuals with partial albinism and one flavistic bat were found there. Proportion of individuals with albinism varied from 0.05% in the case of M. nattereri, 0.02% in the case of M. daubentonii and only 0.007% in the case of M. myotis. During the studies on bat swarming in the Tatra Mountains one case of leucistic whiskered bat was recorded which accounts for 0.016% out of over 5,900 representatives of this species that were caught. Aberrant colouration in bats is rarely recorded in Poland and it is not associated with any particular geographical region. Higher probability of observing atypically coloured individuals occurs in large populations of bats.

Abstract:

(Uploaded by Plazi for the Bat Literature Project) Abstract Chromatic disorders in bats are being reported worldwide at an increasing rate. However, there is widespread misunderstanding and misuse of the associated terminology and concepts in the scientific literature. We conducted an extensive assessment and standardisation of published and unpublished cases of chromatic disorders in bats worldwide. Chromatic disorders have been recorded in at least 609 bats belonging to 115 species and 10 families (after correction of misused terms, 152 cases of albinism, 11 of leucism, 269 of piebaldism, 20 of hypomelanism, three of partial melanism and 94 of melanism; a further 60 records remain unclassified). Of the 354 records in which a location was given, 297 bats were found in closed roost sites, mainly caves, buildings, and mines and galleries, while just three were found roosting externally. This difference could be attributed to the greater monitoring effort employed in underground areas than in forests, and to the greater detectability of bats dwelling in caves and buildings than forest‐dwelling species. Although reports of chromatic disorders in bats are reasonably well spread around the globe, there are large areas from which no disorders have ever been reported: the Central Amazon, almost all of Africa, northern Europe, and almost all of Asia and Oceania. This is likely to be attributable to either the disregard for information on chromatic disorders (e.g. Central Amazon) or to the low abundance of occurring species (e.g. northern Europe). In all, 40% of the records of leucism and piebaldism were misclassified as 'partial albinism'; leucism was also often used to designate pied aberrations. We propose a standardised classification to distinguish between albinism, leucism, piebaldism, hypomelanism, melanism and partial melanism. Due to frequent confusion, we encourage scientists to follow this classification and we highlight the need to employ comprehensive terminology when describing chromatic disorders in scientific publications.

Of the 354 records in which a location was given, 297 bats were found in closed roost sites, mainly caves, buildings, and mines and galleries, while just three were found roosting externally. This difference could be attributed to the greater monitoring effort employed in underground areas than in forests, and to the greater detectability of bats dwelling in caves and buildings than forest‐dwelling species. Although reports of chromatic disorders in bats are reasonably well spread around the globe, there are large areas from which no disorders have ever been reported: the Central Amazon, almost all of Africa, northern Europe, and almost all of Asia and Oceania. This is likely to be attributable to either the disregard for information on chromatic disorders (e.g. Central Amazon) or to the low abundance of occurring species (e.g. northern Europe). In all, 40% of the records of leucism and piebaldism were misclassified as 'partial albinism'; leucism was also often used to designate pied aberrations. We propose a standardised classification to distinguish between albinism, leucism, piebaldism, hypomelanism, melanism and partial melanism. Due to frequent confusion, we encourage scientists to follow this classification and we highlight the need to employ comprehensive terminology when describing chromatic disorders in scientific publications.

Abstract:

Vitiligo is a variant of hypochromia — a skin pigmentation disorder. In this condition, there is a disorder in the synthesis of a special substance of melanin, which is responsible for the pigmentation of the skin, by melanocyte cells located in the basal layer of the epidermis. Melanocytes are evenly distributed throughout the body, with the exception of the soles and palms. Vitiligo is a so-called partial hypochromia and manifests itself as areas of the body that are devoid of pigmentation. More rarely, there is a total pigmentation disorder called albinism. It should be noted that in both hypochromia and albinism, the number of melanocytes is not changed, but for some reason they stop producing melanin from its precursor tyrosine.

Abstract:

Albinism is defined as the complete absence of pigment in skin, hair, and eyes directly caused by a hereditary disorder in the production of melanin. This genetic abnormality is usually attributed to environmental factors such as low quality of habitat and inbreeding. In this note, we recorded a case of partial albinism in a raccoon (Procyon lotor) captured by poachers in the area known as Barranca de Matlacobatl, Municipality of Teocelo, Veracruz, Mexico. The specimen was recovered by the civil association Pro-Vida Silvestre Teocelotl and sheltered for a week under medical care. This is the second record in Mexico of a wild albino raccoon. Specifically, it was recorded particularly for a neotropical region of the center of the state of Veracruz, Mexico.

Abstract:

Melanin pigment helps protect our body from broad wavelength solar radiation and skin cancer. Among other pigmentation disorders in humans, albinism is reported to manifest in both syndromic and nonsyndromic forms as well as with varying inheritance patterns. Oculocutaneous albinism (OCA), an autosomal recessive nonsyndromic form of albinism, presents as partial to complete loss of melanin in the skin, hair, and iris. OCA has been known to be caused by pathogenic variants in seven different genes, so far, according to all the currently published population studies. However, the detection rate of alleles causing OCA varies from 50% to 90%. One of the significant challenges of uncovering the pathological variant underlying disease etiology is inter- and intra-familial locus heterogeneity. This problem is especially pertinent in highly inbred populations. As examples of such familial locus heterogeneity, we present nine consanguineous Pakistani families with segregating OCA due to variants in one or two different known albinism-associated genes. All of the identified variants are predicted to be pathogenic, which was corroborated by several in silico algorithms and association with diverse clinical phenotypes. We report an individual affected with OCA carries heterozygous, likely pathogenic variants in TYR and OCA2, raising the question of a possible digenic inheritance. Altogether, our study highlights the significance of exome sequencing for the complete genetic diagnosis of inbred families and provides the ramifications of potential genetic interaction and digenic inheritance of variants in the TYR and OCA2 genes.

This study reports the capture of a partial albino scalloped hammerhead Sphyrna lewini in Puerto Madero, Chiapas, Mexico. The specimen was a neonate female that measured 491 mm total length and had a total weight of 800 g. This is the first report of an albino scalloped hammerhead Sphyrna lewini in the Pacific Ocean and the second in the world. The presence of albinism could be the result of multifactorial events, although anthropogenic stressors such as excessive fishing pressure and marine pollution might be involved.

Abstract:

Chédiak–Higashi syndrome (CHS), a rare autosomal recessive disorder associated with leukocyte dysfunction, is characterised by partial skin and hair albinism, immunodeficiency, and abnormal bleeding. Furthermore, it may be associated with cognitive and neurological impairments. The long-term prognosis of patients is generally poor, and haematopoietic stem cell transplantation is a radical immunodeficiency treatment. Here, we report a case of successful oral management of an 18-year-old woman with CHS accompanied by aggressive periodontitis who underwent haematopoietic stem cell transplantation.

Abstract:

Griscelli syndrome (GS) is a rare autosomal recessive disorder characterized by immunodeficiency and partial albinism. Asymmetric crying facies (ACF) is caused by congenital hypoplasia or agenesis of the depressor anguli oris muscle. Asymmetric crying facies may be isolated or it may be associated with various anomalies. We report a 3-month-old Turkish boy who had clinical and microscopic hair features of GS associated with ACF. To the best of our knowledge, this is the 1st case of this association to be reported in the literature.

Abstract:

Griscelli syndrome (GS) is a rare autosomal recessive disorder classified as an inborn error of immunity. Among its three variants, GS type 2, caused by mutations in the RAB27A gene, is marked by partial albinism and recurrent episodes of hemophagocytic lymphohistiocytosis (HLH). This case report chronicles the poignant journey of two siblings tragically lost to this condition. GS type 2 carries a high mortality rate, primarily due to HLH complications. Currently, hematopoietic stem cell transplantation (HSCT) remains the sole curative treatment for this devastating syndrome.
