Genes affected

FABP4 (HGNC:3559): (fatty acid binding protein 4) FABP4 encodes the fatty acid binding protein found in adipocytes. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. It is thought that FABPs roles include fatty acid uptake, transport, and metabolism. [provided by RefSeq, Jul 2008]

The c.263A>C (p.D88A) alteration is located in exon 3 (coding exon 3) of the FABP4 gene. This alteration results from a A to C substitution at nucleotide position 263, causing the aspartic acid (D) at amino acid position 88 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
