Sep 14, 2021

The c.2483T>C (p.V828A) alteration is located in exon 13 (coding exon 12) of the PPP1R13L gene. This alteration results from a T to C substitution at nucleotide position 2483, causing the valine (V) at amino acid position 828 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
