Gene: CCDC141Removed the Q2_21_expert_review tag as expert opinion was received on the rating of this gene from a clinical expert from Genomics England.Created: 5 Oct 2022, 11:33 p.m. | Last Modified: 5 Oct 2022, 11:33 p.m.

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is not associated with a phenotype in OMIM or Gene2Phenotype.
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.
After discussing with the Genomics England Clinical Team, it was decided that this gene should have an Amber rating as variants. Helen Brittain (Genomics England):
"...variants in this gene may be seen as a risk allele (either with other known contributory genetic factors, or unexplained variable penetrance)."Created: 23 Mar 2021, 9:07 a.m. | Last Modified: 23 Mar 2021, 9:07 a.m.

A consanguineous family had a homozygous nonsense variant, but also had a homozygous missense in FEZF1. 3 other families reported with heterozygous variants, but other variants in other genes present. In an olfactory mouse model, Ccdc141 is expressed in GnRH neurons and olfactory fibers and that knockdown of Ccdc141 reduces GnRH neuronal migration.
