Variant summary

Our verdict is The variant received 1 classification points (ACMG Germline Pathogenicity v2019). PM2BP4

The NM_138431.3(SLC33A2):c.595C>T (p.Arg199Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant is present but has an allele frequency of zero in the gnomAD population database. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★).
