The c.607A>C (p.K203Q) alteration is located in exon 4 (coding exon 3) of the VASH2 gene. This alteration results from a A to C substitution at nucleotide position 607, causing the lysine (K) at amino acid position 203 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
