Genes affected

ENSG00000253859 (HGNC:):

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]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0163 (2488/152258) while in subpopulation NFE AF= 0.0224 (1523/68004). AF 95% confidence interval is 0.0215. There are 35 homozygotes in gnomad4. There are 1291 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 35 gene
