The c.585C>A (p.D195E) alteration is located in exon 5 (coding exon 4) of the RAB3A gene. This alteration results from a C to A substitution at nucleotide position 585, causing the aspartic acid (D) at amino acid position 195 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
