Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.1054A>G (p.S352G) alteration is located in exon 8 (coding exon 7) of the RABGAP1 gene. This alteration results from a A to G substitution at nucleotide position 1054, causing the serine (S) at amino acid position 352 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
