Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.1202A>G (p.N401S) alteration is located in exon 12 (coding exon 11) of the ARHGAP28 gene. This alteration results from a A to G substitution at nucleotide position 1202, causing the asparagine (N) at amino acid position 401 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
