The c.1028C>T (p.A343V) alteration is located in exon 11 (coding exon 10) of the ARHGAP28 gene. This alteration results from a C to T substitution at nucleotide position 1028, causing the alanine (A) at amino acid position 343 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
