Differences of Sex Development

Gene: CCDC141

I don't know

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.
