Collection Method: clinical testing

The c.1726A>G (p.I576V) alteration is located in exon 2 (coding exon 1) of the KLHL25 gene. This alteration results from a A to G substitution at nucleotide position 1726, causing the isoleucine (I) at amino acid position 576 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
