Genes affected

RNH1 (HGNC:10074): (ribonuclease/angiogenin inhibitor 1) Placental ribonuclease inhibitor (PRI) is a member of a family of proteinaceous cytoplasmic RNase inhibitors that occur in many tissues and bind to both intracellular and extracellular RNases (summarized by Lee et al., 1988 [PubMed 3219362]). In addition to control of intracellular RNases, the inhibitor may have a role in the regulation of angiogenin (MIM 105850). Ribonuclease inhibitor, of 50,000 Da, binds to ribonucleases and holds them in a latent form. Since neutral and alkaline ribonucleases probably play a critical role in the turnover of RNA in eukaryotic cells, RNH may be essential for control of mRNA turnover; the interaction of eukaryotic cells with ribonuclease may be reversible in vivo.[supplied by OMIM, Jul 2010]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.740T>C (p.L247P) alteration is located in exon 7 (coding exon 5) of the RNH1 gene. This alteration results from a T to C substitution at nucleotide position 740, causing the leucine (L) at amino acid position 247 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
