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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.788T>C (p.F263S) alteration is located in exon 8 (coding exon 7) of the SOAT1 gene. This alteration results from a T to C substitution at nucleotide position 788, causing the phenylalanine (F) at amino acid position 263 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
