The c.400A>G (p.N134D) alteration is located in exon 3 (coding exon 3) of the GSPT1 gene. This alteration results from a A to G substitution at nucleotide position 400, causing the asparagine (N) at amino acid position 134 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
