The c.1057C>A (p.L353I) alteration is located in exon 8 (coding exon 8) of the GSPT1 gene. This alteration results from a C to A substitution at nucleotide position 1057, causing the leucine (L) at amino acid position 353 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
