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]

NDRG4 Gene-Disease associations (from GenCC):

• achromatopsia

  Inheritance: AR Classification: LIMITED Submitted by: G2P
