Nov 10, 2022

The c.11T>G (p.F4C) alteration is located in exon 1 (coding exon 1) of the KIFC2 gene. This alteration results from a T to G substitution at nucleotide position 11, causing the phenylalanine (F) at amino acid position 4 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
