I don't know

CPE is not associated with any phenotype on OMIM or Gene2Phenotype. PMID: 26120850 reported on a consanguineous Sudanese family with Mendelian pattern of obesity. The proband had childhood onset obesity, ID, T2DM and hypogonadotrophic hypogonadism and was homozygous for truncating mutation. There were 4 other family members who were heterozygous for this variant who were mildly obese but did not have ID or hypogonadotrophic hypogonadism. The proband's phenotype resembles Cpe knockout mouse and fat/fat mouse models. However, there is currently not enough evidence to support a gene-disease association.

Variants in this GENE are reported as part of current diagnostic practice

Ellen McDonagh (Genomics England Curator)

Comment on list classification: Candidate gene. Gene added by expert reviewer. CPE knockout mice become obese within 10-14 weeks, and develop endocrinological and behavioral deficits (PMID: 15358678, 15870393). Several publications linking variants in the gene to atherosclerosis. Gene not associated with a disease/phenotype in OMIM, Gene2Phenotype, Orphanet or DECIPHER. Obesity HPO term not associated with CPE. No single variants in ClinVar reported in CPE...only structural variants that include this gene and others.
