The c.56C>T (p.A19V) alteration is located in exon 1 (coding exon 1) of the SS18 gene. This alteration results from a C to T substitution at nucleotide position 56, causing the alanine (A) at amino acid position 19 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
