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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.355A>G (p.K119E) alteration is located in exon 5 (coding exon 5) of the CBX7 gene. This alteration results from a A to G substitution at nucleotide position 355, causing the lysine (K) at amino acid position 119 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
