Sep 01, 2024

The c.1117G>C (p.V373L) alteration is located in exon 4 (coding exon 3) of the KLHL33 gene. This alteration results from a G to C substitution at nucleotide position 1117, causing the valine (V) at amino acid position 373 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
