| 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 |

| Differences of Sex Development v0.27 | KLB |
Zornitza Stark gene: KLB was added gene: KLB was added to Disorders of Sex Differentiation. Sources: Literature Mode of inheritance for gene: KLB was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: KLB were set to 28754744 Phenotypes for gene: KLB were set to Hypogonadotropic hypogonadism Review for gene: KLB was set to GREEN Added comment: Seven heterozygous loss‐of‐function KLB mutations in 13 individuals reported. In mice, lack of Klb led to delayed puberty, altered estrous cyclicity, and subfertility due to a hypothalamic defect associated with inability of GnRH neurons to release GnRH in response to FGF21. Functional analysis showed decreased activity in response to FGF21 and FGF8. KLB is an obligate coreceptor for FGF21 alongside FGFR1. Sources: Literature |
