Genes affected

FABP2 (HGNC:3556): (fatty acid binding protein 2) The protein encoded by this gene is an intracellular fatty acid-binding protein that participates in the uptake, intracellular metabolism, and transport of long-chain fatty acids. The encoded protein is also involved in the modulation of cell growth and proliferation. This protein binds saturated long-chain fatty acids with high affinity, and may act as a lipid sensor to maintain energy homeostasis. [provided by RefSeq, Aug 2017]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.4492882E-6).
• BP6: Variant 4-119320747-T-C is Benign according to our data. Variant chr4-119320747-T-C is described in ClinVar as [Benign]. Clinvar id is 16494.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.764 is higher than 0.05.
