The c.686T>C (p.I229T) alteration is located in exon 5 (coding exon 5) of the RAB3IP gene. This alteration results from a T to C substitution at nucleotide position 686, causing the isoleucine (I) at amino acid position 229 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
