Genes affected

MPHOSPH8 (HGNC:29810): (M-phase phosphoprotein 8) Enables chromatin binding activity and methylated histone binding activity. Involved in negative regulation of single stranded viral RNA replication via double stranded DNA intermediate; regulation of DNA methylation; and regulation of gene expression. Located in several cellular components, including cytosol; heterochromatin; and nuclear lumen. Part of nucleosome. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 12, 2024

The c.664A>G (p.K222E) alteration is located in exon 3 (coding exon 3) of the MPHOSPH8 gene. This alteration results from a A to G substitution at nucleotide position 664, causing the lysine (K) at amino acid position 222 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
