Genes affected

RRP9 (HGNC:16829): (ribosomal RNA processing 9, U3 small nucleolar RNA binding protein) This gene encodes a member of the WD-repeat protein family. The encoded protein is a component of the nucleolar small nuclear ribonucleoprotein particle (snoRNP) and is essential for 18s rRNA processing during ribosome synthesis. It contains seven WD domains required for nucleolar localization and specific interaction with the U3 small nucleolar RNA (U3 snoRNA). [provided by RefSeq, Oct 2012]

The c.722G>T (p.R241L) alteration is located in exon 8 (coding exon 8) of the RRP9 gene. This alteration results from a G to T substitution at nucleotide position 722, causing the arginine (R) at amino acid position 241 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
