Dec 18, 2023

The c.5237T>C (p.I1746T) alteration is located in exon 40 (coding exon 40) of the KIF13B gene. This alteration results from a T to C substitution at nucleotide position 5237, causing the isoleucine (I) at amino acid position 1746 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
