Genes affected

NDRG2 (HGNC:14460): (NDRG family member 2) This gene is a member of the N-myc downregulated gene family which belongs to the alpha/beta hydrolase superfamily. The protein encoded by this gene is a cytoplasmic protein that may play a role in neurite outgrowth. This gene may be involved in glioblastoma carcinogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2017]

The c.668A>G (p.H223R) alteration is located in exon 11 (coding exon 9) of the NDRG2 gene. This alteration results from a A to G substitution at nucleotide position 668, causing the histidine (H) at amino acid position 223 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
