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.

Nov 17, 2022

The c.57G>A (p.M19I) alteration is located in exon 1 (coding exon 1) of the FABP1 gene. This alteration results from a G to A substitution at nucleotide position 57, causing the methionine (M) at amino acid position 19 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
