Genes affected
RPS17 (HGNC:10397): (ribosomal protein S17) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of four RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 40S subunit. The protein belongs to the S17E family of ribosomal proteins and is located in the cytoplasm. Mutations in this gene cause Diamond-Blackfan anemia 4. Alternative splicing of this gene results in multiple transcript variants. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Apr 2014]

Diamond-Blackfan anemia Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2015The p.M1? pathogenic mutation (also known as c.2T>G), located in coding exon 1 of the RPS17 gene, results from a T to G substitution at nucleotide position 2. This alters the methionine residue at the initiation codon. This mutation was found de novo in a patient with typical anemia, dysmorphic facial features, and short stature and was not observed in 71 healthy controls (Cmejla et al 2007. Hum Mutat.28(12):1178-82). A different mutation in the same codon (c.1A>G) was reportedly identified in a Korean patient with DBA (Song MJ, Pediatr Blood Cancer 2010 Apr; 54(4):629-31). In addition to the clinical data presented in the literature, since sequence variations that modify the initiation codon (ATG) are expected to result in either loss of translation initiation or N-terminal truncation, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294). -
