Genes affected

RRP8 (HGNC:29030): (ribosomal RNA processing 8) Enables methylated histone binding activity. Involved in several processes, including cellular response to glucose starvation; intrinsic apoptotic signaling pathway by p53 class mediator; and regulation of gene expression. Located in several cellular components, including cytosol; nuclear lumen; and rDNA heterochromatin. Part of chromatin silencing complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method:clinical testing

The c.892C>T (p.R298C) alteration is located in exon 3 (coding exon 3) of the RRP8 gene. This alteration results from a C to T substitution at nucleotide position 892, causing the arginine (R) at amino acid position 298 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
