The c.101A>G (p.E34G) alteration is located in exon 2 (coding exon 1) of the RABGAP1 gene. This alteration results from a A to G substitution at nucleotide position 101, causing the glutamic acid (E) at amino acid position 34 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
