Genes affected

GPRASP1 (HGNC:24834): (G protein-coupled receptor associated sorting protein 1) This gene encodes a member of the GPRASP (G protein-coupled receptor associated sorting protein) family. The protein may modulate lysosomal sorting and functional down-regulation of a variety of G-protein coupled receptors. It targets receptors for degradation in lysosomes. The receptors interacting with this sorting protein include D2 dopamine receptor (DRD2), delta opioid receptor (OPRD1), beta-2 adrenergic receptor (ADRB2), D4 dopamine receptor (DRD4) and cannabinoid 1 receptor (CB1R). Multiple alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, May 2010]

The c.1156A>C (p.K386Q) alteration is located in exon 6 (coding exon 1) of the GPRASP1 gene. This alteration results from a A to C substitution at nucleotide position 1156, causing the lysine (K) at amino acid position 386 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
