The c.689A>T (p.Q230L) alteration is located in exon 7 (coding exon 7) of the KIF19 gene. This alteration results from a A to T substitution at nucleotide position 689, causing the glutamine (Q) at amino acid position 230 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
