The c.539A>C (p.N180T) alteration is located in exon 1 (coding exon 1) of the STRBP gene. This alteration results from a A to C substitution at nucleotide position 539, causing the asparagine (N) at amino acid position 180 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
