May 31, 2023

The c.629T>C (p.I210T) alteration is located in exon 2 (coding exon 2) of the KBTBD4 gene. This alteration results from a T to C substitution at nucleotide position 629, causing the isoleucine (I) at amino acid position 210 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
