Genes affected

SETD5 (HGNC:25566): (SET domain containing 5) This function of this gene has yet to be determined but based on sequence similarity to other SET domain proteins it may function as a histone methyltransferase. Mutations in this gene have been associated with an autosomal dominant form of intellectual disability. Alternative splicing results in multiple transcript variants encoding different isoforms.

ACMG classification

Our verdict: Pathogenic. The variant received 18 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
• PP5: Variant 3-9474583-G-A is Pathogenic according to our data. Variant chr3-9474583-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 1075980.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
