The c.2171C>T (p.A724V) alteration is located in exon 19 (coding exon 19) of the TTC13 gene. This alteration results from a C to T substitution at nucleotide position 2171, causing the alanine (A) at amino acid position 724 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
