The c.418A>G (p.M140V) alteration is located in exon 1 (coding exon 1) of the RABGAP1L gene. This alteration results from a A to G substitution at nucleotide position 418, causing the methionine (M) at amino acid position 140 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
