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]

The c.1062T>A (p.D354E) alteration is located in exon 5 (coding exon 5) of the RRP8 gene. This alteration results from a T to A substitution at nucleotide position 1062, causing the aspartic acid (D) at amino acid position 354 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
