Genes affected

AGPAT5 (HGNC:20886): (1-acylglycerol-3-phosphate O-acyltransferase 5) This gene encodes a member of the 1-acylglycerol-3-phosphate O-acyltransferase family. This integral membrane protein converts lysophosphatidic acid to phosphatidic acid, the second step in de novo phospholipid biosynthesis. A pseudogene of this gene is present on the Y chromosome.

Ambry Genetics

Nov 06, 2023

The c.342T>A (p.H114Q) alteration is located in exon 3 (coding exon 3) of the AGPAT5 gene. This alteration results from a T to A substitution at nucleotide position 342, causing the histidine (H) at amino acid position 114 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
