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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.233C>T (p.A78V) alteration is located in exon 1 (coding exon 1) of the SH3BGR gene. This alteration results from a C to T substitution at nucleotide position 233, causing the alanine (A) at amino acid position 78 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
