not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.571G>A (p.V191M) alteration is located in exon 4 (coding exon 3) of the RABGAP1 gene. This alteration results from a G to A substitution at nucleotide position 571, causing the valine (V) at amino acid position 191 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
