Genes affected

PRDM5 (HGNC:9349): (PR/SET domain 5) The protein encoded by this gene is a transcription factor of the PR-domain protein family. It contains a PR-domain and multiple zinc finger motifs. Transcription factors of the PR-domain family are known to be involved in cell differentiation and tumorigenesis. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0185 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 4-120695145-TG-T is Pathogenic according to our data. Variant chr4-120695145-TG-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 981043.Status of the report is criteria_provided_single_submitter, 1 stars.
