Arthrogryposis multiplex congenita (AMC) is a rare disorder characterized by non-progressive, multiple contractures. In addition to affected extremities, patients may also present microstomia, decreased temporomandibular joint mobility. Although the etiology of AMC is unclear, any factor that decreases fetal movement is responsible for AMC. Thus, accurate diagnosis and classification are crucial to the appropriate treatment of AMC. The development of ultrasound technology has enabled prenatal diagnosis. Very early treatment is favorable, and multidisciplinary treatment is necessary to improve the function of AMC patients...

The world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy. In these countries, buffalo genetic breeding programs have been performed for many decades. The occurrence of congenital malformations has caused a slowing of the genetic progress and economic loss for the breeders, due to the death of animals, or damage to their reproductive ability or failing of milk production. Moreover, they cause animal welfare reduction because they can imply foetal dystocia and because the affected animals have a reduced fitness with little chances of survival...

The ongoing Zika virus outbreak in South, Central, and, most recently, North America has become a global health care emergency. Originally thought to be a benign, self-limiting viral syndrome, the newest epidemic has provided convincing evidence that maternal Zika virus infection can lead to neonatal malformations, the so-called congenital Zika syndrome. The alarming number of microcephalic neonates being born during the current outbreak is most notable, though several other anomalies, such as arthrogryposis, redundant scalp tissue, and cranial collapse, have been reported...

BACKGROUND: Arthrogryposis syndromes are a heterogeneous group of disorders characterized by congenital joint contractures often requiring multiple surgeries during childhood to address skeletal and visceral abnormalities. Previous reports suggest that these children have increased perioperative risk, including hypermetabolic events discrete from malignant hyperthermia, difficult airway management, isolated hyperthermia, and difficult IV line placement. We sought to compare children with arthrogryposis multiplex congenita (AMC) versus the less severe, distal arthrogryposis syndromes (DAS) and to evaluate possible intraoperative hyperthermia of patients with AMC...

The semaphorins constitute a large family of secreted and membrane-associated proteins that regulate many developmental processes, including neural circuit assembly, bone formation and angiogenesis. Recently, bi-allelic loss-of-function variants in SEMA3A (semaphorin 3A) were identified in a single patient with a particular pattern of multiple congenital anomalies (MCA). Using homozygosity mapping combined with exome sequencing, we identified a homozygous SEMA3A variant causing a premature stop codon in an 8-year-old boy with the same pattern of MCA...

Zika virus (ZIKV) is a mosquito-borne arbovirus from the Flaviviridae family. It had caused several epidemics since its discovery in 1947, but there was no significant attention to this virus until the recent outbreak in Brazil in 2015. The main concern is the causal relationship between prenatal ZIKV infection and congenital microcephaly, which has been confirmed recently. Moreover, ZIKV may cause other central nervous system abnormalities such as brain parenchymal atrophy with secondary ventriculomegaly, intracranial calcification, malformations of cortical development (such as polymicrogyria, and lissencephaly-pachygyria), agenesis/hypoplasia of the corpus callosum, cerebellar and brainstem hypoplasia, sensorineural hearing-loss, and ocular abnormalities as well as arthrogryposis in the infected fetuses...

BACKGROUND: Severe hip contractures in arthrogrypsosis are multiplanar, which can preclude or can greatly complicate sitting and ambulation. The reorientational osteotomy at the intertrochanteric level preserves preoperative hip motion but moves it to a more functional domain. We retrospectively compared preoperative and postoperative hip motion and evaluated the ambulatory abilities of patients who underwent the procedure. METHODS: Since 2008, 65 patients with arthrogryposis had 119 reorientational proximal femoral osteotomies with a minimum follow-up of 2 years...

We report the case of a newborn with arthrogryposis multiplex congenita and severe axial hypotonia without cardiac involvement in which, using a customized targeted next-generation sequencing assay for 64 myopathy-associated genes, we detected a novel homozygous truncating mutation, c.38661_38665del, in exon 197 of the TTN gene that is expressed only in the fetal skeletal isoform. Its pathogenicity is supported by evidence of maternal isodisomy for chromosome 2. Muscle pathology showed fibers with core-like areas devoid of oxidative staining and cytoplasmic bodies...

Here we report three patients with severe palmoplantar keratoderma associated with ichthyosis and sensorineural deafness. Bi-allelic mutations were found in VPS33B, encoding VPS33B, a Sec1/Munc18 family protein which interacts with Rab11a and Rab25 proteins and is involved in trafficking of the collagen modifying enzyme LH3. Two patients were homozygous for the missense variant p.Gly131Glu, whilst one patient was compound heterozygous for p.Gly131Glu and the splice site mutation c.240-1G>C, previously reported in patients with Arthrogryposis Renal dysfunction and Cholestasis syndrome...

The recent alarming statements concerning the newborn ZIKV-induced microcephaly epidemics in the Northeast of Brazil, released by the Brazilian Ministry of Health, as well as important international health agencies, such as the World Health Organization and the Pan American Health Organization, raised many "why and how" questions so far, that will hopefully be scientifically answered, as more researches in that regard come up in the long term. In this paper, we describe another potentially ZIKV-induced central nervous system and musculoskeletal disorder that has accompanied microcephaly in these children: atrhogryposis multiplex congenita...

ARC syndrome (arthrogryposis - renal dysfunction - cholestasis) is a rare lethal multisystemic autosomal recessive disease. A newborn of consanguineous parents of Algerian descent presented cholestatic jaundice, dehydration, and Fanconi syndrome at 10 days of life. The blood smear showed a very characteristic gray appearance of platelets. A homozygous mutation was evidenced in the VPS33B gene. This gene codes for a protein involved in trafficking of intracellular vesicles. The mutation (c.604-2A>G) present in the heterozygous state in the parents affects an invariant base of the splice acceptor site and to our knowledge has not been reported yet...

The genetic work-up of arthrogryposis is challenging due to the diverse clinical and molecular etiologies. We report a-18(3/12)-year-old boy, from a 2nd degree consanguineous family, who presented at 3(6/12) years with hypotonia, distal laxity, contractures, feeding difficulties at birth. He required surgery for progressive scoliosis at 16 years of age, and walked independently since then with an unstable gait and coordination defects. His latest examination at 18 years of age revealed a proprioceptive defect and loss-of-joint position sense in the upper limbs...

Arthrogryposis multiplex congenital (AMC) is a heterogeneous disorder, characterized by nonprogressive multiple intra-articular contractures, which can be recognized at birth. The prevalence in Europe is estimated at about 1 per 12,000. Etiopathogenesis of arthrogryposis is multifactorial. Symptoms of some forms of arthrogryposis can be found in the clinical presentation of selected genetic disorders, e.g. Pena Shokeir syndrome. Arthrogryposis can also result from environmental factors such as medication, trauma or chronic illness during pregnancy, as well as from oligohydramnios or abnormal structure of the uterus...

OBJECTIVE: We studied a series of patients with fetal akinesia deformation sequence (FADS)/arthrogryposis multiplex congenita (AMC), with nemaline bodies on muscle specimens, which revealed mutations in the NEB gene. METHOD: We pathologically assessed seven cases from three families, who presented with AMC/FADS. Targeted genetic analysis for Ashkenazi Jewish mutation (in relevant patients) was followed by next-generation sequencing and multiplex ligation-dependent probe amplification...

The sodium leak channel, a Na(+)-permeable, nonselective cation channel, is widely expressed in the nervous system, contributing a basal Na(+)-leak conductance and regulating neuronal excitability. A 3-year-old girl, heterozygous for a de novo missense mutation in NALCN (c.956C>T; p.Ala319Val) predicted to be deleterious, presented from birth with: stimulus-induced, episodic contractures of the limbs and face with associated respiratory distress; distal arthrogryposis; severe axial hypotonia; and severe global developmental delay (CLIFAHDD syndrome)...

To compare the timing of subperiosteal new bone formation (SPNBF) and callus formation in femoral shaft fractures that occurred at birth between neonates with and without an underlying disease, we retrospectively evaluated the radiographs of 12 neonates with femoral fractures on birth day. Seven had no underlying disease, 3 had osteogenesis imperfecta, 1 had myotonic dystrophy, and 1 had arthrogryposis. We evaluated the timing of initial SPNBF/soft callus/hard callus formation. In neonates without an underlying disease, SPNBF and callus formation were not detected by day 6 on radiographs; SPNBF/soft callus/hard callus formation was first observed at day 14...
