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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 24, 2023The c.976G>A (p.V326I) alteration is located in exon 3 (coding exon 3) of the MPHOSPH8 gene. This alteration results from a G to A substitution at nucleotide position 976, causing the valine (V) at amino acid position 326 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
