Description

The c.1300T>G (p.L434V) alteration is located in exon 14 (coding exon 12) of the ITCH gene. This alteration results from a T to G substitution at nucleotide position 1300, causing the leucine (L) at amino acid position 434 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
