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.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0013678968).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.327 is higher than 0.05.
