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 GeneticsJan 09, 2024The c.806A>G (p.Y269C) alteration is located in exon 1 (coding exon 1) of the MC5R gene. This alteration results from a A to G substitution at nucleotide position 806, causing the tyrosine (Y) at amino acid position 269 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
