Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.408G>A (p.M136I) alteration is located in exon 6 (coding exon 5) of the ARHGAP28 gene. This alteration results from a G to A substitution at nucleotide position 408, causing the methionine (M) at amino acid position 136 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
