Testo completoThe development of the gonadotropic axis (HHG) begins during fetal life but is not completed until puberty. Numerous players are involved at each stage, and a defect in any one of them can lead to pubertal pathologies or fertility disorders in adulthood. Genetic factors play a central role in the development of the HHG axis, and the genetic study of pubertal pathologies has led to major advances in our understanding of the underlying molecular mechanisms, although there are still many unknowns. For my thesis work, I chose to explore the genetics of pubertal diseases in order to better understand the etiopathogenic mechanisms of these complex disorders. First, I had the opportunity to study a consanguineous family in which two sisters showed an absence of puberty associated with increased concentrations of estradiol and gonadotropins. We identified a rare homozygous variant in the estradiol receptor alpha (ERalpha). In vitro study of the mutated receptor showed a decrease of its regulatory activity on a promoter containing Estradiol Response Elements, as well as a paradoxical ligand-independent activation of the KISS1 promoter. The study of these cases provides a better understanding of the consequences of ERalpha loss-of-function mutations and the regulatory mechanisms exerted by estradiol via ERalpha. Next, I focused on the genetics of central precocious puberty (CPP), and in particular the MKRN3 (Makorin ring finger protein 3) gene, since its mutations are the most common genetic cause of CPP. MKRN3 is a maternally imprinted gene whose protein function is unknown. Determining the pathogenicity of CPP-associated missense variants relies almost exclusively on in silico analyses. In this part of my work, I have shown that the usual in silico analysis tools do not efficiently determine the pathogenicity of rare MKRN3 missense variants. I have also proposed a new approach to annotate the pathogenicity of variants based on the analysis of MKRN3 mutational constraint and amino acid conservation within the MKRN protein family. Maternally inherited CPP accounts for the majority of familial CPP and is not explained by a mutation in MKRN3. I aimed to identify new genes involved in maternally inherited CPP, based on the hypothesis that a major gene might exist in a monogenic model. For this purpose, I selected 27 patients from 18 families in whom analysis of a panel of genes associated with CPP was non-contributory. Analysis of variants in coding regions combined with genome-wide copy number variation (CNV) analysis led to the identification of candidate genes whose frequency was assessed on a replicative cohort of 48 patients by high-throughput sequencing (NGS). This analysis failed to identify a major gene. However, we did identify loss-of-function variants in two genes for which mouse hypothalamic expression analysis showed a decrease during the juvenile phase, suggesting their involvement in the post-natal control of HHG axis maturation. This study shows that CPP is a complex genetic disease. My research provides a better understanding of the clinical and biological consequences of loss of ERalpha function. It confirms the complexity of genetic control of development and maturation of the HHG axis. Finally, it shows that the annotation of variants for pubertal diseases is complex and that current in-silico analyses are not adapted to the study of CPP
