Genes affected

EFTUD2 (HGNC:30858): (elongation factor Tu GTP binding domain containing 2) This gene encodes a GTPase which is a component of the spliceosome complex which processes precursor mRNAs to produce mature mRNAs. Mutations in this gene are associated with mandibulofacial dysostosis with microcephaly. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

EFTUD2 Gene-Disease associations (from GenCC):

• mandibulofacial dysostosis-microcephaly syndrome

  Inheritance: AD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: G2P, Orphanet, Labcorp Genetics (formerly Invitae), ClinGen
