The c.1532A>G (p.N511S) alteration is located in exon 14 (coding exon 12) of the TERB1 gene. This alteration results from a A to G substitution at nucleotide position 1532, causing the asparagine (N) at amino acid position 511 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
