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
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 7 ACMG points.
PVS1
?
Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.03665639 fraction of the gene. Cryptic splice site detected, with MaxEntScore 7, offset of 0 (no position change), new splice context is: gaaGTatgt. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
?
Very rare variant in population databases, with high coverage;
