The c.1761C>G (p.H587Q) alteration is located in exon 13 (coding exon 12) of the RABGAP1 gene. This alteration results from a C to G substitution at nucleotide position 1761, causing the histidine (H) at amino acid position 587 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
