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]

The c.334G>A (p.A112T) alteration is located in exon 4 (coding exon 4) of the AWAT1 gene. This alteration results from a G to A substitution at nucleotide position 334, causing the alanine (A) at amino acid position 112 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
