“…We identified 9 novel PLXNA3 variants. A genotype-phenotype correlation could be suggested by the observation that all six PLXNA3 patients with variants coding for amino acid changes in the Plexin A3 cytoplasmic domain (exons [22][23][24][25][26][27][28][29][30][31][32] showed severe neurodevelopmental disorder phenotypes (two-tailed Fisher's exact test, p = 0.0097). None of the variants reported in this study were found in ClinVar (NM_017514.5).…”

“…Des mutations hétérozygotes touchant des gènes de la voie de signalisation des sémaphorines de classe 3 ont été identifiées chez des patients présentant un déficit congénital en GnRH (hypogonadisme hypogonadotrope congénital) [10][11][12] et chez certains patients souffrant d'une obésité précoce sévère [13]. Cependant, contrairement aux patients atteints d'hypogonadisme hypogonadotrope et porteurs de mutations du gène codant la neuropiline-1, ou aux souris mutantes chez lesquelles toutes les cellules qui expriment normalement ce gène ne l'expriment plus [10,11] (Figure 3), les animaux rendus génétiquement déficients en neuropiline-1 uniquement dans les neurones produisant la GnRH n'ont pas de déficit en GnRH, et présentent au contraire une maturation prématurée de ces neurones et une puberté précoce [9] (Figure 4).…”

“…Kotan and colleagues also detected SEMA3F expression in human embryos alongside VN and TN axons, also suggesting a role for this semaphorin signaling in human puberty onset and reproduction [164]. However, phenotypic analysis of Sema3f -−/− mice previously demonstrated that SEMA3F is dispensable for nasal axon patterning and GnRH neuron migration [155].…”

“…Further, variants in SEMA3F (chr 3221.31) and its preferential receptor PLXNA3 (chr Xq28) were recently found in 15 patients belonging to 11 independent families with normosmic CHH/KS [164]. PLXNA3 is believed to undergo random X-inactivation [165].…”
