Genes affected

GPR162 (HGNC:16693): (G protein-coupled receptor 162) This gene was identified upon genomic analysis of a gene-dense region at human chromosome 12p13. It appears to be mainly expressed in the brain; however, its function is not known. Alternatively spliced transcript variants encoding different isoforms have been identified.

The c.68G>T (p.C23F) alteration is located in exon 2 (coding exon 1) of the GPR162 gene. This alteration results from a G to T substitution at nucleotide position 68, causing the cysteine (C) at amino acid position 23 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
