Genes affected

RPL3 (HGNC:10332): (ribosomal protein L3) Ribosomes, the complexes that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 60S subunit. The protein belongs to the L3P family of ribosomal proteins and it is located in the cytoplasm. The protein can bind to the HIV-1 TAR mRNA, and it has been suggested that the protein contributes to tat-mediated transactivation. This gene is co-transcribed with several small nucleolar RNA genes, which are located in several of this gene's introns. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Jul 2008]

RPL3 links:

SNORD139 (HGNC:50421): (small nucleolar RNA, C/D box 139) Intronic regions of ribosomal protein genes can harbor noncoding small nucleolar RNAs (snoRNAs), like U86, which are generated during pre-mRNA processing. snoRNAs form part of the small nucleolar ribonucleoprotein particles (snoRNPs) involved in pre-rRNA processing and modification. snoRNAs of the box C/D class, like U86, function in 2-prime-O-ribose methylation of rRNAs (Duga et al., 2000 [PubMed 10684968]).[supplied by OMIM, Mar 2008]

The c.400T>C (p.C134R) alteration is located in exon 4 (coding exon 4) of the RPL3 gene. This alteration results from a T to C substitution at nucleotide position 400, causing the cysteine (C) at amino acid position 134 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
