Collection Method: clinical testing

The c.674A>C (p.D225A) alteration is located in exon 8 (coding exon 6) of the SPATS2 gene. This alteration results from a A to C substitution at nucleotide position 674, causing the aspartic acid (D) at amino acid position 225 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
