The c.805C>T (p.R269W) alteration is located in exon 4 (coding exon 1) of the GPR19 gene. This alteration results from a C to T substitution at nucleotide position 805, causing the arginine (R) at amino acid position 269 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
