Collection Method: clinical testing

The c.444C>A (p.N148K) alteration is located in exon 1 (coding exon 1) of the GPR37L1 gene. This alteration results from a C to A substitution at nucleotide position 444, causing the asparagine (N) at amino acid position 148 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
