The c.932G>T (p.W311L) alteration is located in exon 2 (coding exon 2) of the GPR37L1 gene. This alteration results from a G to T substitution at nucleotide position 932, causing the tryptophan (W) at amino acid position 311 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
