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 GeneticsApr 19, 2023The c.748C>G (p.H250D) alteration is located in exon 6 (coding exon 5) of the AGPAT4 gene. This alteration results from a C to G substitution at nucleotide position 748, causing the histidine (H) at amino acid position 250 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
