Genes affected

FABP1 (HGNC:3555): (fatty acid binding protein 1) This gene encodes the fatty acid binding protein found in liver. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. This protein and FABP6 (the ileal fatty acid binding protein) are also able to bind bile acids. It is thought that FABPs roles include fatty acid uptake, transport, and metabolism.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.110G>A (p.G37E) alteration is located in exon 2 (coding exon 2) of the FABP1 gene. This alteration results from a G to A substitution at nucleotide position 110, causing the glycine (G) at amino acid position 37 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
