Genetics has driven significant discoveries in the field of neurodegenerative diseases (NDDs). An emerging theme in neurodegeneration warrants an urgent and comprehensive update: that carrier status of early-onset autosomal recessive (AR) disease, typically considered benign, is associated with an increased risk of a spectrum of late-onset NDDs. Glucosylceramidase beta (GBA1) gene mutations, responsible for the AR lysosomal storage disorder Gaucher disease, are a prominent example of this principle, having been identified as an important genetic risk factor for Parkinson disease. Genetic analyses have revealed further examples, notably GRN, TREM2, EIF2AK3, and several other LSD and mitochondria function genes. In this Review, we discuss the evidence supporting the strikingly distinct allele-dependent clinical phenotypes observed in carriers of such gene mutations and its impact on the wider field of neurodegeneration.

AbstractProgressive family intrahepatic cholestasis (PFIC) is an autosomal recessive disease that causes chronic cholestasis. It is associated with pathogenic variants in genes that encode proteins involved in bile secretion to canaliculus from hepatocytes. In this study, we present a 16-year-old boy who presented with severe pruritus and cholestatic jaundice. All possible infectious etiologies were negative. A liver biopsy was consistent with intrahepatic cholestasis and portal fibrosis. DNA was isolated from a peripheral blood sample, and whole exome sequencing was performed. A novel c.3484G > T/p.Glu162Ter variant in the ABCB11 gene and a c.208G> A/p.Asp70Asn variant in the ATP8B1 gene were detected. Despite traditional treatment, the patient's recurrent severe symptoms did not improve. The patient was referred for a liver transplantation. This novel c.3484G > T/p.Glu162Ter variant is associated with a severe and recurrent presentation, and the two compound variants could explain the severity of PFIC.

Mammalian zinc metalloenzymes include alkaline phosphatase. Zinc plays a crucial role in nucleic acid metabolism. RNA and DNA polymerases and thymidine kinase are zinc-dependent enzymes. Zinc deficiency in North America is most clearly seen in the disease acrodermatitis enteropathica. This is an autosomal recessive disease due to a zinc metabolic error—not well defined—which leads to zinc deficiency. Clinical manifestations include a rash around orifices, alopecia, and diarrhea. The laboratory can demonstrate hypozincemia and hypozincuria. Clinical and biochemical remission occurs with oral zinc administration.(R.H.R.)

Afibrinogenemia is a rare bleeding disorder with an estimated prevalence of 1:10,00,000 [1, 2]. It is an autosomal recessive disease resulting from mutations in any of the 3 genes that encodes the 3 polypeptide chains of fibrinogen and are located on the long arm of chromosome 4 3. Spontaneous bleeding, bleeding after minor trauma, and excessive bleeding during interventional procedures are the principal manifestations [2, 4]. Here we have reviewed the process of diagnosing a case of such rare disorder in Apollo Hospitals Dhaka. We have also highlighted the treatment and management plan of such a case.DOI: http://dx.doi.org/10.3329/pulse.v4i1.6964Pulse Vol.4 January 2010 p.34-35

Malignancy Potential

Abstract Defined as a tumour with increased malignancy potential in childhood, medulloblastoma was first reported in the literature by Percival Bailey and Harvey Cushing in 1925. Scientific studies over the years have shown that this type of tumour represents about 20% of all intracranial tumours encountered in childhood, their percentage decreasing with advancing age. The genetic factor plays an important part in the appearance of medulloblastoma; there are certain diseases, in the patient’s history, that can be associated with this type of tumour. Here, we can specify Turcot syndrome (an autosomal recessive disease, rarely encountered) or basal cell carcinoma syndrome. This article presents the case of a young patient (41-year-old) suffering from a cerebellar tumour formation that turned out to be, after histopathological examination, a medulloblastoma. In practice we can find several types of medulloblastoma (desmoplastic or nodular, anaplastic, classical or undifferentiated). In what follows I will try to highlight a few aspects of a classic medulloblastoma.

Respiratory Rehabilitation

Cystic fibrosis (CF) is a complex, systemic autosomal recessive disease that affects the functions of the respiratory system, the digestive tract and all exocrine glands. The frequency for Europe averages 1: 2500 to 1: 3500 live births. The total number of patients with cystic fibrosis in Bulgaria is about 180. About 10% of the patients are diagnosed at birth. About 60–70% of patients are diagnosed before they reach one year of age. Respiratory symptoms predominate in the clinical picture in patients with cystic fibrosis and determine the prognosis in more than 90% of the patients. The treatment of patients with cystic fibrosis is strictly individualized, pharmacological and non-pharmacological and requires a comprehensive therapeutic approach. The complex therapy also includes bronchodilators, NSAIDs, corticosteroids, respiratory rehabilitation in combination with general body massage. Continued courses of broad-spectrum antibiotics are required to suppress chronic infection. With the progression of the disease, complications such as atelectasis, pneumothorax and pulmonary hemorrhages are observed. The establishment of specialized centers with trained and experienced professionals is essential in order to provide optimal patient care. These include frequent clinical evaluations, follow-up of complications, and early interventions for the treatment of patients with cystic fibrosis. The aim of the article is to familiarize the audience with the therapeutic measures applied in the treatment of patients with cystic fibrosis.

Mode Of Inheritance

In 1970,1 1971,2 and 19743 we described two families, each with two siblings who had atresia of the first portion of the duodenum. The four patients were first cousins to each other. We suggested a genetic etiology with an autosomal recessive mode of inheritance, which has been accepted.4 The source of the proposed gene for both families was traced to a single individual. Recently, a third family, linked to the previous two with strong consanguineous ties, had a pair of twins affected with the same anomaly. The purpose of this article is to bring the weight of new evidence afforded by this third family to further substantiate the genetic etiology of this condition.

Shwachman-Diamond syndrome (SDS) is a rare, inherited, autosomal recessive disease characterized by exocrine pancreatic dysfunction, skeletal problems and varying degrees of cytopenias resulting in bone marrow dysfunction. We report the first case of SDS that was difficult to distinguish from celiac disease because this is a valuable example of the variety in SDS presentation.

Keops Complex

AbstractThe KEOPS complex, which is conserved across archaea and eukaryotes, is composed of four core subunits; Pcc1, Kae1, Bud32 and Cgi121. KEOPS is crucial for the fitness of all organisms examined. In humans, pathogenic mutations in KEOPS genes lead to Galloway–Mowat syndrome, an autosomal-recessive disease causing childhood lethality. Kae1 catalyzes the universal and essential tRNA modification N6-threonylcarbamoyl adenosine, but the precise roles of all other KEOPS subunits remain an enigma. Here we show using structure-guided studies that Cgi121 recruits tRNA to KEOPS by binding to its 3’ CCA tail. A composite model of KEOPS bound to tRNA reveals that all KEOPS subunits form an extended tRNA-binding surface that we have validated in vitro and in vivo to mediate the interaction with the tRNA substrate and its modification. These findings provide a framework for understanding the inner workings of KEOPS and delineate why all KEOPS subunits are essential.
