| Mendeliome v1.2452 | EFNA4 |
Bryony Thompson changed review comment from: Supporting animal models, but no compelling evidence in human cases. There’s no supporting segregation evidence and most of the variants reports to date are more common than expected for a dominant disease. PMID: 34586326 - 3 missense variants identified in a cohort of 101 children with non-syndromic craniosynostosis (EFNA4, c.178C>T: p.His60Tyr - 361 hets & 2 homs in gnomAD v2.1, c.283A>G: p.Lys95Glu, c.349C>A: Pro117Thr - 337 hets in gnomAD v2.1). All 3 variants were present in at least one non-affected family member PMID: 23983218, 33065355 - Efna4 KO mouse line demonstrates skeletal variance. Homozygous Epha4 null mice had substantially less trabecular bone in femur and vertebra compared to wild-type controls PMID: 29215649 - 1 missense variant (c.211G>A, p.(Glu71Lys) - 7 hets in gnomAD v2.1) identified in a unicoronal craniosynostosis case in a cohort of 309 craniosynostosis cases PMID: 29168297 - 1 missense variant (c.550C>T; p.(Leu184Phe) - 1 het in gnomAD v2.1) in a metopic craniosynostosis case from a cohort of 391 single suture craniosynostosis cases. The variant was inherited from an unaffected parent. PMID: 19772933 - a de novo 1.4 Mb microdeletion of chromosome 1q21.3, including EFNA1, EFNA3 and EFNA4, was identified in a child with moderate mental retardation, microcephaly, arching eyebrows, low set ears, long eyelashes, persistent fetal pads and clinodactyly. PMID: 19201948 - EphA4 -/- mutant mice exhibit defects in the coronal suture and neural crest-mesoderm boundary that phenocopy those of Twist1+/- mice. The EphA4 +/- mice were similar to the wild-type controls. PMID: 16540516 - 3 variants (178C>T p.His60Tyr - 361 hets & 2 homs in gnomAD v2.1; c.349C>A p.Pro117Thr - 337 hets in gnomAD v2.1; frameshift 471_472delCCinsA) in cohort of 81 non-syndromic coronal synostosis cases. 2 of the variants were inherited from unaffected parents and Pro117Thr was de novo (confirmed). In vitro functional assays demonstrated partial or complete loss of function for the missense variants. Fibroblasts from the patient with the frameshift expressed in an alternatively spliced minor isoform of EFNA4.; to: Supporting animal models, but no compelling evidence in human cases has been reported since 2006.
