Genes affected
AGPAT4 (HGNC:20885): (1-acylglycerol-3-phosphate O-acyltransferase 4) 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. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 25, 2022The c.418G>A (p.E140K) alteration is located in exon 4 (coding exon 3) of the AGPAT4 gene. This alteration results from a G to A substitution at nucleotide position 418, causing the glutamic acid (E) at amino acid position 140 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
