Collection Method: clinical testing

The c.794T>C (p.L265S) alteration is located in exon 15 (coding exon 11) of the LRMP gene. This alteration results from a T to C substitution at nucleotide position 794, causing the leucine (L) at amino acid position 265 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
