Collection Method: clinical testing

The c.217T>A (p.C73S) alteration is located in exon 3 (coding exon 1) of the KLHL29 gene. This alteration results from a T to A substitution at nucleotide position 217, causing the cysteine (C) at amino acid position 73 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
