<em>Ferri-iron of methemoglobin (MetHb) is a rare disorder associated with the oxidation of divalent ferro-iron of hemoglobin (Hb). Both acquired and hereditary processes can result from methemoglobinemia. The most prevalent types are acquired ones, primarily as a result of exposure to chemicals that directly or indirectly oxidize Hb. Inherited forms are due either to autosomal recessive variants in the CYB5R3 gene or to autosomal dominant variants in the globin genes, collectively </em><em>termed as HbM disease. </em>

An overview of the genetic variation in arthropods that transmit pathogens to vertebrates is presented, emphasizing the genetics of vector-pathogen relationships and the biochemical genetics of vectors.

Susceptibility to pathogens is controlled by maternally inherited factors, sex-linked dominant alleles, and dominant and recessive autosomal genes.

MODY (maturity-onset diabetes of the young) is an autosomal dominant form of diabetes that is usually manifested before the 25-year of life. This type of diabetes is caused by defects in the primary insulin secretion. There are several types of MODY, which are monogenic diseases, where mutations in a single gene are responsible for a particular type of MODY. Currently, there are eleven types of MODY, from which the most common types are MODY 2 and MODY 3 (with mutations on GCK and HNF1A genes, respectively).

A panel of thirteen genes was analyzed: L1CAM (SPG1), PLP1 (SPG2), ATL1 (SPG3A), SPAST (SPG4), CYP7B1 (SPG5A), SPG7 (SPG7), KIF5A (SPG10), SPG11 (SPG11), ZYFVE26 (SPG15), REEP1 (SPG31), ATP13A2 (SPG78), DYNC1H1, and BICD2 using a next generation sequencing-based technique.

Abstract:
Gene-poor, repeat-rich regions of the genome are poorly understood and have been understudied due to technical challenges and the misconception that they are degenerating “junk.” Yet multiple lines of evidence indicate these regions may be an important source of variation that could drive adaptation and species divergence, particularly through regulation of fertility. The ∼40 Mb Y chromosome of Drosophila melanogaster contains only 16 known protein-coding genes, and is highly repetitive and entirely heterochromatic. Most of the genes originated from duplication of autosomal genes and have redu

It is a major cause of congestive heart failure and the most frequent indication for heart transplantation.
