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

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
• BP6: Variant 17-44851334-G-A is Benign according to our data. Variant chr17-44851334-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 2961855.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=1.13 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000263 (4/152318) while in subpopulation SAS AF = 0.000415 (2/4820). AF 95% confidence interval is 0.000073. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 37 AD gene.
