Genes affected
RRP1 (HGNC:18785): (ribosomal RNA processing 1) The protein encoded by this gene is the putative homolog of the yeast ribosomal RNA processing protein RRP1. The encoded protein is involved in the late stages of nucleologenesis at the end of mitosis, and may be required for the generation of 28S rRNA. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.291G>C (p.Q97H) alteration is located in exon 4 (coding exon 4) of the RRP1 gene. This alteration results from a G to C substitution at nucleotide position 291, causing the glutamine (Q) at amino acid position 97 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
