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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 09, 2024The c.799G>A (p.D267N) alteration is located in exon 7 (coding exon 6) of the AGPAT4 gene. This alteration results from a G to A substitution at nucleotide position 799, causing the aspartic acid (D) at amino acid position 267 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
