Genes affected

GPR26 (HGNC:4481): (G protein-coupled receptor 26) This gene encodes a G protein-couple receptor protein. G-protein-coupled receptors are a large family of membrane proteins that are involved in cellular responses to environmental stimuli, neurotransmitters, and hormones. The encoded protein may play a role in neurodegenerative diseases. Epigenetic silencing of this gene has been observed in gliomas. [provided by RefSeq, Sep 2016]

The c.532G>A (p.A178T) alteration is located in exon 1 (coding exon 1) of the GPR26 gene. This alteration results from a G to A substitution at nucleotide position 532, causing the alanine (A) at amino acid position 178 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
