The c.53A>C (p.K18T) alteration is located in exon 1 (coding exon 1) of the DDX19A gene. This alteration results from a A to C substitution at nucleotide position 53, causing the lysine (K) at amino acid position 18 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
