The c.575C>T (p.A192V) alteration is located in exon 2 (coding exon 2) of the SAPCD2 gene. This alteration results from a C to T substitution at nucleotide position 575, causing the alanine (A) at amino acid position 192 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
