Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.530C>T (p.S177F) alteration is located in exon 7 (coding exon 6) of the ARHGAP28 gene. This alteration results from a C to T substitution at nucleotide position 530, causing the serine (S) at amino acid position 177 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
