Genes affected
MRPS2 (HGNC:14495): (mitochondrial ribosomal protein S2) Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 28S subunit protein that belongs to the ribosomal protein S2 family. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, May 2012]

PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PS3-Very Strong => PS3 upgraded in strength to Very Strong (https://www.ncbi.nlm.nih.gov/pubmed/29576219). -

Mitochondrial respiratory chain complexes (I and IV) deficiencies were found in both patients. Typical clinical features of mitochondrial disorders (hyperlactatemia, hypoglycemia, hearing loss, neurological abnormaliites). The Arg110Cys variant fulfils the criteria to be classified as pathogenic on the basis of segregation studies, absence in controls and functional evidence. -
