- Function
- Component of the small ribosomal subunit (PubMed:23636399). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23636399). Required for pre- rRNA processing and maturation of 40S ribosomal subunits (PubMed:16990592). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. During the assembly of the SSU processome in the nucleolus, many ribosome biogenesis factors, an RNA chaperone and ribos... (Source: Uniprot)

HI Disease:
- DIAMOND-BLACKFAN ANEMIA 1; DBA1 Monarch
HI Evidence:

PUBMED:
10590074
Willig et al. in 1999 were the first to describe the relationship between Diamond-Blackfan anemia (DBA) and RPS19 loss of functions variants. They described 11 nonsense variants and 15 indels. They also described several RPS19 missense mutations, splicing defects and intronic variants in individuals with similar phenotypes. Most of those patients had DBA without other clinical manifestations, and they were all considered sporadic cases with confirmed de novo variants. A minority of cases also presented facial malformations, head circumference alterations, intellectual disability, kidney malformation and short stature.

PUBMED:

Gazda et al. in 2004 described several patients with Diamond-Blackfan anemia and loss of function (LoF) variants. Among those patients, 14 different variants were identified, including seven de novo LoF variants. They also demonstrated those variants reduced RPS19 mRNA and protein levels in CD34+ bone marrow cells suggesting haploinsufficiency as a disease mechanism.

PUBMED:
15059149
Orfali et al. in 2004 described 104 families from United Kingdom with DBA including 16 (15%) with RPS19 variants, including 4 de novo loss of function variants.

PUBMED:
20960466
Boria et al. in 2010 described a DBA Mutation Database consisting in hundreds of variants in 9 different genes including RPS19, which is the most frequently mutated gene in patients with DBA. The DBA Mutation Database registered 129 distinct RPS19 variants carried by 219 patients: 82 of these are de novo and 45 are inherited. The authors themselves reported several additional variants, including 3 nonsense,18 indels and 10 splice-site defects.
HI Evidence Comments:
Whole gene deletions, as well as intragenic mutations of RPS19, are known to cause Diamond-Blackfan anemia by a pathogenic mechanism of haploinsufficiency. See GeneReviews for relevant primary literature and review.
