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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.94G>T (p.A32S) alteration is located in exon 1 (coding exon 1) of the RRP15 gene. This alteration results from a G to T substitution at nucleotide position 94, causing the alanine (A) at amino acid position 32 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
