The c.515C>T (p.A172V) alteration is located in exon 7 (coding exon 7) of the ARHGAP44 gene. This alteration results from a C to T substitution at nucleotide position 515, causing the alanine (A) at amino acid position 172 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
