Ambry Genetics

Apr 28, 2022

The c.1138C>T (p.R380W) alteration is located in exon 8 (coding exon 8) of the RAB3IP gene. This alteration results from a C to T substitution at nucleotide position 1138, causing the arginine (R) at amino acid position 380 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
