Collection Method: clinical testing

The c.458A>G (p.K153R) alteration is located in exon 5 (coding exon 5) of the LCN6 gene. This alteration results from a A to G substitution at nucleotide position 458, causing the lysine (K) at amino acid position 153 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
