The c.631G>A (p.V211I) alteration is located in exon 2 (coding exon 2) of the GPR37L1 gene. This alteration results from a G to A substitution at nucleotide position 631, causing the valine (V) at amino acid position 211 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
