Genetic Variant SCRT2:p.Gly137Ser (chr20-664186-C-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_033129.4(SCRT2):c.409G>A(p.Gly137Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G137D) has been classified as Uncertain significance.

Genes affected

SCRT2 (HGNC:15952): (scratch family transcriptional repressor 2) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in negative regulation of extrinsic apoptotic signaling pathway via death domain receptors and negative regulation of transcription by RNA polymerase II. Predicted to act upstream of or within regulation of neuron migration. Predicted to be located in chromatin. [provided by Alliance of Genome Resources, Apr 2022]
