Genes affected
MC5R (HGNC:6933): (melanocortin 5 receptor) This gene encodes a member of the seven-pass transmembrane G protein-coupled melanocortin receptor protein family that stimulate cAMP signal transduction. The encoded protein is a receptor for melanocyte-stimulating hormone and adrenocorticotropic hormone and is suggested to play a role in sebum generation. [provided by RefSeq, Jun 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.749G>T (p.C250F) alteration is located in exon 1 (coding exon 1) of the MC5R gene. This alteration results from a G to T substitution at nucleotide position 749, causing the cysteine (C) at amino acid position 250 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
