Genes affected

GPR33 (HGNC:4489): (G protein-coupled receptor 33) This gene has been identified as an orphan chemoattractant G-protein-coupled receptors (GPCR) pseudogene. Studies have shown that the inactivated gene is present as the predominant allele in the human population. A small fraction of the human population has been found to harbor an intact allele.[provided by RefSeq, Oct 2010]

The c.400G>C (p.V134L) alteration is located in exon 2 (coding exon 1) of the GPR33 gene. This alteration results from a G to C substitution at nucleotide position 400, causing the valine (V) at amino acid position 134 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
