Genes affected

NDRG4 (HGNC:14466): (NDRG family member 4) 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 is required for cell cycle progression and survival in primary astrocytes and may be involved in the regulation of mitogenic signalling in vascular smooth muscles cells. Alternative splicing results in multiple transcripts encoding different isoforms.[provided by RefSeq, Jun 2011]

Collection Method: clinical testing

The c.232C>T (p.P78S) alteration is located in exon 4 (coding exon 4) of the NDRG4 gene. This alteration results from a C to T substitution at nucleotide position 232, causing the proline (P) at amino acid position 78 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
