The c.158A>G (p.Y53C) alteration is located in exon 1 (coding exon 1) of the GPR137B gene. This alteration results from a A to G substitution at nucleotide position 158, causing the tyrosine (Y) at amino acid position 53 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
