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.

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, EFTUD2
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.953
• PP5: Variant 17-44859132-A-C is Pathogenic according to our data. Variant chr17-44859132-A-C is described in ClinVar as [Pathogenic]. Clinvar id is 30404.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr17-44859132-A-C is described in Lovd as [Pathogenic].
