Genes affected

RRP15 (HGNC:24255): (ribosomal RNA processing 15 homolog) This gene encodes a protein that co-purifies with human nucleoli. A similar protein in budding yeast is a component of pre-60S ribosomal particles, and is required for the early maturation steps of the 60S subunit. [provided by RefSeq, Jul 2008]

Aug 16, 2021

The c.65A>T (p.K22M) alteration is located in exon 1 (coding exon 1) of the RRP15 gene. This alteration results from a A to T substitution at nucleotide position 65, causing the lysine (K) at amino acid position 22 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
