Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2023The c.217A>G (p.M73V) alteration is located in exon 3 (coding exon 2) of the RABGAP1 gene. This alteration results from a A to G substitution at nucleotide position 217, causing the methionine (M) at amino acid position 73 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
