Genes affected
SH3RF1 (HGNC:17650): (SH3 domain containing ring finger 1) This gene encodes a protein containing an N-terminus RING-finger, four SH3 domains, and a region implicated in binding of the Rho GTPase Rac. Via the RING-finger, the encoded protein has been shown to function as an ubiquitin-protein ligase involved in protein sorting at the trans-Golgi network. The encoded protein may also act as a scaffold for the c-Jun N-terminal kinase signaling pathway, facilitating the formation of a functional signaling module. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.2497A>G (p.R833G) alteration is located in exon 11 (coding exon 10) of the SH3RF1 gene. This alteration results from a A to G substitution at nucleotide position 2497, causing the arginine (R) at amino acid position 833 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
