| Differences of Sex Development v0.293 | AXL |
Zornitza Stark gene: AXL was added gene: AXL was added to Differences of Sex Development. Sources: Expert Review Mode of inheritance for gene: AXL was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: AXL were set to 24476074 Phenotypes for gene: AXL were set to Hypogonadotropic hypogonadism, MONDO:0018555, AXL-related Review for gene: AXL was set to RED Added comment: Four variants reported in individuals with KS/IHH. One is non-canonical splice site variant (c.586-6 C>T) but authors demonstrate no abnormal splicing occurs. Remainder are missense. Segregation in one family only: inherited from phenotypically normal parent. Axl null mice demonstrated delay in first estrus and the interval between vaginal opening and first estrus Sources: Expert Review |

| Differences of Sex Development v0.284 | CCDC141 |
Zornitza Stark gene: CCDC141 was added gene: CCDC141 was added to Differences of Sex Development. Sources: Expert Review Mode of inheritance for gene: CCDC141 was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal Publications for gene: CCDC141 were set to 251920460; 28324054; 32520725; 27014940 Phenotypes for gene: CCDC141 were set to congenital hypogonadotropic hypogonadism, MONDO:0015770, CCDC141-related Review for gene: CCDC141 was set to AMBER Added comment: PMID: 251920460 describes 2 affected siblings from a consanguineous family with anosmic HH, who had homozygous variant in FEZF1 (Amber gene on this panel) and also homozyous for variant in CCDC141. PMID: 28324054 describes the above case and also 3 new cases (all had normal sense of smell and HH). Family 2: compound het for CCDC141 and heterozygous for DMXL2 variant. Family 3: heterozygous for CCDC141 variant and heterozygous for variants in 3 other genes (NR5A2, FSHB - Green on HH panel, IGSF10). Family 4: affected patient was heterozygous for CCDC141 variant, which the father also carried but father was unaffected. PMID: 32520725 describes a large Chinese cohort with congenital HH looking at the contribution of CCDC141 to the disease. 12 probands had variants CCDC141 and 9 of these probands had variants in other HH-related genes (inluding PCSK1, ANOS1, PROKR2, AXL, SOX10, HS6ST1, PNPLA6 and FGFR1). The authors concluded that CCDC141 variants alone is not sufficient to cause HH. PMID: 27014940 talks about a ccdc141 knockdown mouse model reduces GnRH neuronal migration. Overall, insufficient evidence for gene-disease association; may be a modifier. Sources: Expert Review |
