The c.590T>C (p.V197A) alteration is located in exon 7 (coding exon 7) of the SP140L gene. This alteration results from a T to C substitution at nucleotide position 590, causing the valine (V) at amino acid position 197 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
