The c.1103A>G (p.K368R) alteration is located in exon 12 (coding exon 12) of the DBF4 gene. This alteration results from a A to G substitution at nucleotide position 1103, causing the lysine (K) at amino acid position 368 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
