Genes affected

SH3BGR (HGNC:10822): (SH3 domain binding glutamate rich protein) Predicted to enable SH3 domain binding activity. Predicted to be involved in protein-containing complex assembly. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

GET1-SH3BGR (HGNC:54635): (GET1-SH3BGR readthrough) This locus represents naturally occurring readthrough transcription between the neighboring WRB (tryptophan rich basic protein) and SH3BGR (SH3 domain binding glutamate-rich protein) genes on chromosome 21. Readthrough transcripts may encode fusion proteins that shares sequence identity with each individual gene product. [provided by RefSeq, Apr 2017]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.195 is higher than 0.05.
