The c.529G>A (p.D177N) alteration is located in exon 1 (coding exon 1) of the STRBP gene. This alteration results from a G to A substitution at nucleotide position 529, causing the aspartic acid (D) at amino acid position 177 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
