Genes affected

PTRHD1 (HGNC:33782): (peptidyl-tRNA hydrolase domain containing 1) This gene encodes the enzyme peptidyl-tRNA hydrolase. Peptidyl-tRNA hydrolases perform the essential function of recycling peptidyl-tRNAs. Mutations in this gene are associated with autosomal-recessive intellectual disability and parkinsonism. [provided by RefSeq, May 2017]

CENPO (HGNC:28152): (centromere protein O) This gene encodes a component of the interphase centromere complex. The encoded protein is localized to the centromere throughout the cell cycle and is required for bipolar spindle assembly, chromosome segregation and checkpoint signaling during mitosis. Alternatively spliced transcript variants encoding multiple protein isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

CENPO (HGNC:):

ACMG classification
