Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_003101.6(SOAT1):​c.1577A>T​(p.Gln526Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 13/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q526R) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 31)
• Consequence: SOAT1 NM_003101.6 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.77

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]
