Genes affected
AWAT1 (HGNC:23252): (acyl-CoA wax alcohol acyltransferase 1) The protein encoded by this gene belongs to the diacylglycerol acyltransferase family. It esterifies long chain (wax) alcohols with acyl-CoA-derived fatty acids to produce wax esters. Wax esters are enriched in sebum, suggesting that this enzyme plays a central role in lipid metabolism in skin. Consistent with this observation, this protein is predominantly expressed in the sebaceous gland of the skin. [provided by RefSeq, Sep 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2024The c.916C>G (p.L306V) alteration is located in exon 7 (coding exon 7) of the AWAT1 gene. This alteration results from a C to G substitution at nucleotide position 916, causing the leucine (L) at amino acid position 306 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
