The c.1982T>G (p.I661S) alteration is located in exon 10 (coding exon 9) of the PPP1R13L gene. This alteration results from a T to G substitution at nucleotide position 1982, causing the isoleucine (I) at amino acid position 661 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
