Genes affected

SETD6 (HGNC:26116): (SET domain containing 6, protein lysine methyltransferase) This gene encodes a methyltransferase that adds a methyl group to the histone H2AZ, which is involved in nuclear receptor-dependent transcription. The protein also interacts with several endogenous proteins which are involved in nuclear hormone receptor signaling. A related pseudogene is located on chromosome 2. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.992

Collection Method: clinical testing

The c.227G>T (p.G76V) alteration is located in exon 2 (coding exon 2) of the SETD6 gene. This alteration results from a G to T substitution at nucleotide position 227, causing the glycine (G) at amino acid position 76 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
