George Washington University School of Medicine and Health Sciences, Washington, DC, USA.

Genetic disorders are in the differential diagnosis when young children present with unexplained fractures or intracranial hemorrhage. For medical and legal reasons, it is imperative to make the correct diagnosis and provide clear, evidence-based explanations of how alternative diagnoses were ruled out. A genetics consultation in cases of suspected child physical abuse should synthesize the history of present illness, medical history, family history, physical examination, and radiologic and laboratory findings in consultation with other specialists.

Occipital Horn Syndrome as a Result of Splice Site Mutations in . No Activity of Splice Variants Missing Exon 10 or Exon 15.

Front Mol Neurosci 2021 21;14:532291. Epub 2021 Apr 21.

Department of Biology, University of Copenhagen, Copenhagen, Denmark.

Disease-causing variants in lead to two different phenotypes associated with copper deficiency; a lethal form called Menkes disease (MD), leading to early death, and a much milder form called occipital horn syndrome (OHS). Some investigators have proposed that an transcript missing exon 10 leads to a partly active protein product resulting in the OHS phenotype. Here, we describe an individual with OHS, a biology professor, who survived until age 62 despite a splice site mutation, leading to skipping of exon 15. Read More

ATP7A mutation with occipital horns and distal motor neuropathy: A continuum.

Eur J Med Genet 2020 Dec 31;63(12):104087. Epub 2020 Oct 31.

Service de génétique, CLAD Ouest, CHU Rennes, Rennes, France; Service de génétique, CRDI, CHU Rennes, Rennes, France.

ATP7A-related copper transport disorders are classically separated in three pathologies according to their severity, all inherited in an X-linked recessive manner: Menkes disease (MD, OMIM #309400) which represent more than 90% of cases; occipital Horn Syndrome (OHS, OMIM #304150) and ATP7A-related distal motor neuropathy also named X-linked distal spinal muscular atrophy-3 (SMAX3, OMIM #300489) (Kennerson et al., 2010). Although there is no clear cut correlation between Cu and ceruloplasmin levels in ATP7A related disorders, these three entities probably represent a continuum partly depending on residual functional ATP7A protein (Møller, 2015).

Cancer Pro-oxidant Therapy Through Copper Redox Cycling: .

Authors:
Manuel Rieber

Curr Pharm Des 2020 ;26(35):4461-4466

IVIC, Cancer Cell Biology Laboratory, CMBC, Caracas 1020A, Venezuela.

Background: Copper (Cu) is a transition metal active in Fenton redox cycling from reduced Cu+ and H2O2, to oxidized Cu2+ and the hydroxyl radical (·OH) highly reactive oxygen species (ROS). At homeostatic Cu levels, ROS promote cell proliferation, migration, angiogenesis, and wound repair. To limit ROS toxicity, cells use Cu-dependent chaperone proteins, Cu-binding ceruloplasmin, and Cu-modulated enzymes like superoxide dismutases (SOD) like SOD1 and SOD3 to scavenge excess superoxide anions which favour Cu+ reduction, and mitochondrial cytochrome c oxidase, important in aerobic energy production.
