Genes affected

DRG2 (HGNC:3030): (developmentally regulated GTP binding protein 2) This gene encodes a GTP-binding protein known to function in the regulation of cell growth and differentiation. Read-through transcripts containing this gene and a downstream gene have been identified, but they are not thought to encode a fusion protein. This gene is located within the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jan 2012]

The c.847C>G (p.L283V) alteration is located in exon 10 (coding exon 10) of the DRG2 gene. This alteration results from a C to G substitution at nucleotide position 847, causing the leucine (L) at amino acid position 283 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
