Collection Method: clinical testing

The c.2068G>A (p.D690N) alteration is located in exon 10 (coding exon 9) of the PPP1R13L gene. This alteration results from a G to A substitution at nucleotide position 2068, causing the aspartic acid (D) at amino acid position 690 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
