Genes affected
GPAM (HGNC:24865): (glycerol-3-phosphate acyltransferase, mitochondrial) This gene encodes a mitochondrial enzyme which prefers saturated fatty acids as its substrate for the synthesis of glycerolipids. This metabolic pathway's first step is catalyzed by the encoded enzyme. Two forms for this enzyme exist, one in the mitochondria and one in the endoplasmic reticulum. Two alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Oct 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2023The c.1954C>A (p.Q652K) alteration is located in exon 1 (coding exon 1) of the GPAM gene. This alteration results from a C to A substitution at nucleotide position 1954, causing the glutamine (Q) at amino acid position 652 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
