AbstractPrimary familial brain calcification (PFBC) is a neurological condition characterized by the presence of intracranial calcifications, mainly involving basal ganglia, thalamus, and dentate nuclei. So far, six genes have been linked to this condition: SLC20A2, PDGFRB, PDGFB, and XPR1 inherited as autosomal-dominant trait, while MYORG and JAM2 present a recessive pattern of inheritance. Patients mainly present with movement disorders, psychiatric disturbances, and cognitive decline or are completely asymptomatic and calcifications may represent an occasional finding. Here we present three variants in SLC20A2, two exonic and one intronic, which we found in patients with PFBC associated to three different clinical phenotypes. One variant is novel and two were already described as variants of uncertain significance. We confirm the pathogenicity of these three variants and suggest a broadening of the phenotypic spectrum associated with mutations in SLC20A2.

Molecular Cytogenetic Techniques

Marfan syndrome is an inherited connective tissue disorder that is transmitted as an autosomal dominant trait. These cases can be diagnosed by molecular cytogenetic techniques. A modified Ghent criteria using systemic scoring system can also identify these cases in absence of molecular cytogenetic techniques.We report a case of a 6 year 5 month old boy who presented with the complaints of excessive sweating sinceinfancy and protrusion of both eye balls which was non progressive since early childhood. On examination, some skeletal features of Marfan syndrome was found and echocardiogram showed huge dilatation of root of aorta which helped in diagnosis by scoring system.Birdem Med J 2014; 4(2): 111-114

Mode Of Inheritance

The Term ichthyosis describes a group of heritable disorders which are characterized by cutaneous scaling. The visible scale differentiates these disorders from xeroderma in which the skin is dry but does not visibly desquamate. Many classifications of the ichthyoses have been proposed, but most are descriptive and contribute little to an understanding of etiology and pathogenesis. Often clinical variants or patients with minor associated anomalies have been categorized separately on an empirical basis and, in some cases, several names have been used for one entity to indicate severity of involvement. The most useful classification appears to be that of Wells and Kerr,1 who segregated the various types by their pattern of inheritance and retained the nomenclature in common usage. Differences in clinical features and histologic patterns also correlate with these genetically distinguishable types. Thus, with careful attention to the distribution and type of scale, family history, and skin histology, the physician will be able to classify patients in a meaningful way. Such an approach is helpful for several reasons. The prognosis, troublesome features, and degree of handicapping differ for the various ichthyoses. Sensible genetic counseling, an important part of the management of such patients, is possible only with the correct diagnosis. Moreover, clinical investigation of affected individuals will be further confused unless the entity under study is well defined. The need for an understanding of the physiologic and biochemical defects of ichthvotic skin is underscored by the limitations of currently available therapy. The four major types of ichthyosis include: (1) ichthyosis vulgaris, transmitted as an autosomal dominant trait; (2) sexlinked ichthyosis, transmitted as an Xlinked trait; (3) bullous congenital ichthyosiform erythroderma (CIE), inherited as an autosomal dominant trait; and (4) nonbulbus congenital ichthyosiform erythroderma, autosomal recessive mode of inheritance (Table I).

Autosomal Dominant Trait

Hereditary amyloid transthyretin (ATTRv) amyloidosis with polyneuropathy is a progressive disease that is transmitted as an autosomal dominant trait and characterized by multiple organ failure, including axonal sensory-motor neuropathy, cardiac involvement, and autonomic dysfunction. Liver transplantation (LT) and combined heart–liver transplantation, introduced in the 1990s, have been the only therapies for almost two decades. In 2011, tafamidis meglumine became the first specific drug approved by regulatory agencies, since then the attention toward this disease has progressively increased and several drugs with different mechanisms of action are now available. This review describes the drugs already on the market, those that have shown interesting results although not yet approved, and those currently being tested.

SUMMARY:Benign familial neonatal convulsions are a rare genetic seizure disorder inherited as an autosomal dominant trait. They consist of brief episodes of seizures, recurring during the first few days or weeks of life in otherwise normal babies; their prognosis is good. We report a family in which at least 12 members in three generations presented with this condition; they all had an excellent outcome.

A multiplex kindred ascertained through a single proband with GTS has been systematically investigated with standardised diagnostic instruments for other cases of GTS and related disorders. Complex segregation analysis supported the hypothesis that a single major gene inherited in autosomal dominant fashion but with incomplete penetrance contributed most of the variance in the liability to develop GTS and related disorders. This result is consistent with previous segregation analyses which have employed different methods of ascertainment, and tends to confirm that a proportion of GTS is due to a dominant gene and is suitable for investigation with genetic markers for linkage analysis.

Pachyonychia Congenita

AbstractThe authores report a case of patient with pachyonychia syndrome, a rare genedermatosis inherited as an autosomal dominant trait, who also had otological lesions beyond the other classic signs and symptoms of the syndrome. Many kinds of treatment have already been proposed, but all failed to show satisfactory results. A new, cheap and easy-to-use treatment was developed in this study, using keratoplastics interpolated with humectant lotion for 90 days. The results after three years of follow-up are still thoroughly satisfactory.
