Genes affected

ST20-MTHFS (HGNC:44655): (ST20-MTHFS readthrough) This locus represents naturally occurring read-through transcription between the neighboring suppressor of tumorigenicity 20 and 5,10-methenyltetrahydrofolate synthetase (5-formyltetrahydrofolate cyclo-ligase) genes on chromosome 15. The read-through transcript produces a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Dec 2010]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.561 is higher than 0.05.
