Genes affected

CBX7 (HGNC:1557): (chromobox 7) This gene encodes a protein that contains the CHROMO (CHRomatin Organization MOdifier) domain. The encoded protein is a component of the Polycomb repressive complex 1 (PRC1), and is thought to control the lifespan of several normal human cells. [provided by RefSeq, Oct 2016]

The c.475C>T (p.R159C) alteration is located in exon 5 (coding exon 5) of the CBX7 gene. This alteration results from a C to T substitution at nucleotide position 475, causing the arginine (R) at amino acid position 159 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
