Genes affected

FTO (HGNC:24678): (FTO alpha-ketoglutarate dependent dioxygenase) This gene is a nuclear protein of the AlkB related non-haem iron and 2-oxoglutarate-dependent oxygenase superfamily but the exact physiological function of this gene is not known. Other non-heme iron enzymes function to reverse alkylated DNA and RNA damage by oxidative demethylation. Studies in mice and humans indicate a role in nervous and cardiovascular systems and a strong association with body mass index, obesity risk, and type 2 diabetes. [provided by RefSeq, Jul 2011]

LOC124903691 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.61).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.373 is higher than 0.05.
