Collection Method: clinical testing

The c.1931C>T (p.A644V) alteration is located in exon 20 (coding exon 15) of the TSGA10 gene. This alteration results from a C to T substitution at nucleotide position 1931, causing the alanine (A) at amino acid position 644 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
