Genes affected
ABR (HGNC:81): (ABR activator of RhoGEF and GTPase) This gene encodes a protein that is similar to the protein encoded by the breakpoint cluster region gene located on chromosome 22. The protein encoded by this gene contains a GTPase-activating protein domain, a domain found in members of the Rho family of GTP-binding proteins. Functional studies in mice determined that this protein plays a role in vestibular morphogenesis. Alternatively spliced transcript variants have been reported for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.1759G>A (p.V587M) alteration is located in exon 16 (coding exon 16) of the ABR gene. This alteration results from a G to A substitution at nucleotide position 1759, causing the valine (V) at amino acid position 587 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
