Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 01, 2022The c.665A>G (p.H222R) alteration is located in exon 5 (coding exon 4) of the RABGAP1 gene. This alteration results from a A to G substitution at nucleotide position 665, causing the histidine (H) at amino acid position 222 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
