The c.869T>C (p.L290S) alteration is located in exon 6 (coding exon 6) of the GSG1L gene. This alteration results from a T to C substitution at nucleotide position 869, causing the leucine (L) at amino acid position 290 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
