Genes affected

SOAT1 (HGNC:11177): (sterol O-acyltransferase 1) The protein encoded by this gene belongs to the acyltransferase family. It is located in the endoplasmic reticulum, and catalyzes the formation of fatty acid-cholesterol esters. This gene has been implicated in the formation of beta-amyloid and atherosclerotic plaques by controlling the equilibrium between free cholesterol and cytoplasmic cholesteryl esters. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 2011]

Oct 19, 2024

The c.751G>T (p.A251S) alteration is located in exon 7 (coding exon 6) of the SOAT1 gene. This alteration results from a G to T substitution at nucleotide position 751, causing the alanine (A) at amino acid position 251 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
