Genes affected

TRMT44 (HGNC:26653): (tRNA methyltransferase 44 homolog) The protein encoded by this gene is a putative tRNA methyltransferase found in the cytoplasm. Defects in this gene may be a cause of partial epilepsy with pericentral spikes (PEPS), but that has not been proven definitively. [provided by RefSeq, May 2012]
