Collection Method: clinical testing

The c.481C>G (p.L161V) alteration is located in exon 1 (coding exon 1) of the GPR37L1 gene. This alteration results from a C to G substitution at nucleotide position 481, causing the leucine (L) at amino acid position 161 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
