Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_001080517.3(SETD5):c.10G>A(p.Ala4Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A4S) has been classified as Uncertain significance.
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.
