Genes affected

SUCNR1 (HGNC:4542): (succinate receptor 1) This gene encodes a G-protein-coupled receptor for succinate, an intermediate molecule of the citric acid cycle. It is involved in the promotion of hematopoietic progenitor cell development, and it has a potential role in renovascular hypertension which has known correlations to renal failure, diabetes and atherosclerosis.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.841C>T (p.R281W) alteration is located in exon 3 (coding exon 2) of the SUCNR1 gene. This alteration results from a C to T substitution at nucleotide position 841, causing the arginine (R) at amino acid position 281 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
