The c.97A>G (p.K33E) alteration is located in exon 2 (coding exon 2) of the DBF4 gene. This alteration results from a A to G substitution at nucleotide position 97, causing the lysine (K) at amino acid position 33 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
