Mendeliome v0.9815 IHH Zornitza Stark Marked gene: IHH as ready
Mendeliome v0.9815 IHH Zornitza Stark Gene: ihh has been classified as Green List (High Evidence).
Mendeliome v0.9814 IHH Zornitza Stark Phenotypes for gene: IHH were changed from to Acrocapitofemoral dysplasia MIM#607778; Brachydactyly, type A1 MIM#112500
Mendeliome v0.9813 IHH Zornitza Stark Publications for gene: IHH were set to
Mendeliome v0.9811 IHH Zornitza Stark Mode of inheritance for gene: IHH was changed from Unknown to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
Mendeliome v0.9779 IHH Ain Roesley reviewed gene: IHH: Rating: GREEN; Mode of pathogenicity: None; Publications: 34530144, 12632327, 32311039, 29155992; Phenotypes: Acrocapitofemoral dysplasia MIM#607778, Brachydactyly, type A1 MIM#112500; Mode of inheritance: BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal; Current diagnostic: yes
Mendeliome v0.8002 SEMA3F Zornitza Stark gene: SEMA3F was added
gene: SEMA3F was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: SEMA3F was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: SEMA3F were set to 33495532
Phenotypes for gene: SEMA3F were set to Hypogonadotropic hypogonadism
Review for gene: SEMA3F was set to GREEN
Added comment: Screened 216 patients with Idiopathic hypogonadotropic hypogonadism by exome sequencing. Identified 10 individuals from 7 families with heterozygous SEMA3F missense variants. In 4 of the kindreds, there was at least one more gene known to be associated with IHH (oligogenecity). Provide unequivocal human embryonic data showing the expression of SEMA3F along the developing human GnRH migratory pathway. SEMA3Fs harboring the P452T, T29M, and T724M missense variants showed impaired SEMA3F secretion in whole cell lysates.

Mendeliome v0.8000 PLXNA3 Zornitza Stark gene: PLXNA3 was added
gene: PLXNA3 was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: PLXNA3 was set to X-LINKED: hemizygous mutation in males, biallelic mutations in females
Publications for gene: PLXNA3 were set to 33495532
Phenotypes for gene: PLXNA3 were set to Hypogonadotropic hypogonadism
Review for gene: PLXNA3 was set to GREEN
Added comment: Screened 216 patients with Idiopathic hypogonadotropic hypogonadism by exome sequencing. Identified 7 individuals from 5 families with hemizygous PLXNA3 missense variants. In 2 of the kindreds, there was at least one more gene known to be associated with IHH (oligogenecity). Data provided with evidence that PLXNA3, a key component of the SEMA3F holoreceptor complex,31 is expressed by the human GnRH and olfactory/vomeronasal systems. S646P variant showed PLXNA3 localization exclusively in the ER, indicating that the variant S646P disrupts cell surface localization of PLXNA3.

Mendeliome v0.3156 AXL Bryony Thompson gene: AXL was added
gene: AXL was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: AXL was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: AXL were set to 18787040; 24476074
Phenotypes for gene: AXL were set to Kallman syndrome; normosmic idiopathic hypogonadotropic hypogonadism
Review for gene: AXL was set to AMBER
Added comment: Axl null mice had delayed first oestrus and persistently abnormal oestrous cyclicality compared with wild-type controls. Only a single study reported screening human cases. In a screen of 104 probands with KS or nIHH, four heterozygous AXL mutations were identified in two KS and two nIHH unrelated subjects (two males and two females). Three of the variants appear to be too common in gnomAD v2.1 given the reported prevalence of KS reported in GeneReviews (1:30,000 in males and 1:125,000 in females): c.587-6C>T (normal splicing in RNA studies, NFE AF 0.0001472), p.Q361P (NFE 0.002560), p.L50F (AJ 0.004405). The other variant p.S202C (4 hets, 1 female in gnomAD v2.1) is rare enough in gnomAD for a dominant disorder. In vitro functional assays were conducted and p.S202C had an significant effect on function, but so did the more common variant p.Q361P.
