Collection Method: clinical testing

The c.139A>G (p.M47V) alteration is located in exon 3 (coding exon 2) of the LEKR1 gene. This alteration results from a A to G substitution at nucleotide position 139, causing the methionine (M) at amino acid position 47 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
