Jan 24, 2024

The c.82G>A (p.D28N) alteration is located in exon 1 (coding exon 1) of the WDR82 gene. This alteration results from a G to A substitution at nucleotide position 82, causing the aspartic acid (D) at amino acid position 28 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
