Collection Method: clinical testing

The c.157C>T (p.L53F) alteration is located in exon 3 (coding exon 1) of the KLHL29 gene. This alteration results from a C to T substitution at nucleotide position 157, causing the leucine (L) at amino acid position 53 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
