Genes affected

ZSWIM7 (HGNC:26993): (zinc finger SWIM-type containing 7) Predicted to enable zinc ion binding activity. Involved in double-strand break repair via homologous recombination and protein stabilization. Part of Shu complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Pathogenic. Variant got 15 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
• PP5: Variant 17-15987265-C-A is Pathogenic according to our data. Variant chr17-15987265-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 1676297.Status of the report is no_assertion_criteria_provided, 0 stars.
