The c.2127A>T (p.K709N) alteration is located in exon 15 (coding exon 15) of the WDR78 gene. This alteration results from a A to T substitution at nucleotide position 2127, causing the lysine (K) at amino acid position 709 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
