Genes affected

RIN3 (HGNC:18751): (Ras and Rab interactor 3) Summary: This protein encoded by this gene is a member of the RIN family of Ras interaction-interference proteins, which are binding partners to the RAB5 small GTPases. The protein functions as a guanine nucleotide exchange for RAB5B and RAB31. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Collection Method:clinical testing

The c.419T>C (p.I140T) alteration is located in exon 4 (coding exon 4) of the RIN3 gene. This alteration results from a T to C substitution at nucleotide position 419, causing the isoleucine (I) at amino acid position 140 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
