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.

SETD5 Gene-Disease associations (from GenCC):

• intellectual disability-facial dysmorphism syndrome due to SETD5 haploinsufficiency

  Inheritance: AD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Orphanet, G2P, Labcorp Genetics (formerly Invitae)
• syndromic complex neurodevelopmental disorder

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-9447834-C-G is Pathogenic according to our data. Variant chr3-9447834-C-G is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 520418.Status of the report is criteria_provided_single_submitter, 1 stars.
