Collection Method: clinical testing

The c.769C>T (p.L257F) alteration is located in exon 1 (coding exon 1) of the GPR31 gene. This alteration results from a C to T substitution at nucleotide position 769, causing the leucine (L) at amino acid position 257 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
