The c.584C>T (p.A195V) alteration is located in exon 7 (coding exon 7) of the SPAG7 gene. This alteration results from a C to T substitution at nucleotide position 584, causing the alanine (A) at amino acid position 195 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
