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

  Inheritance: AD Classification: DEFINITIVE Submitted by: ClinGen

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
