Genes affected

PUS3 (HGNC:25461): (pseudouridine synthase 3) The protein encoded by this gene catalyzes the formation of tRNA pseudouridine from tRNA uridine at position 39 in the anticodon stem and loop of transfer RNAs. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]

HYLS1 (HGNC:26558): (HYLS1 centriolar and ciliogenesis associated) This gene encodes a protein localized to the cytoplasm. Mutations in this gene are associated with hydrolethalus syndrome. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Oct 2008]

HYLS1 Gene-Disease associations (from GenCC):
