Biotinidase deficiency is an autosomal recessive genetic disorder which is not uncommon in the Saudi population. Biotinidase is responsible for biotin recycling and biotin is an essential cofactor for activation of the carboxylase enzymes. Absence of biotinidase leads to infantile or early childhood encephalopathy, seizure disorder, dermatitis, alopecia, neural deafness and optic atrophy. The disease can be diagnosed by simple fluorometric enzyme assay. Treatment with biotin is both cheap and simple, resulting in rewarding clinical recovery and normalization of the biochemical, neuroradiological and neurophysiological parameters. If neglected, however, a patient may die of acute metabolic acidosis or may suffer from permanent neural deafness and optic atrophy, with mental and motor handicap. We describe the detection and treatment of 20 cases of biotinidase deficiency in our hospital and recommend the introduction of a neonatal screening programme for this disorder

Sinonasal Polyposis

Cystic fibrosis (CF) is a common autosomal recessive genetic disorder where a deletion mutation and subsequent downstream alteration in transmembrane regulator proteins results in increased mucus viscosity. CF manifests clinically with chronic multisystem inflammation and recurrent infections. Nearly all children with CF have chronic sinusitis, and a large majority will have concurrent sinonasal polyposis. Chronic sinusitis and sinonasal polyposis in pediatric patients with CF can be managed conservatively initially, though most will fail medical management and require surgical intervention. Unfortunately, symptom resolution is marginal and polyp recurrence rates are high. Currently, no cure exists for CF and the mainstay of treatment is to provide symptomatic relief, and minimize disease morbidity.

Tay–Sachs disease is a genetic disorder that results in the destruction of nerve cells in the brain and spinal cord..also known as GM2 gangliosidosis or Hexosaminidase A deficiency) is an autosomal recessive genetic disorder. In its most common variant known as infantile Tay-Sachs disease it presents with a relentless deterioration of mental and physical abilities which commences at 6 months of age and usually results in death by the age of four.It is caused by a genetic defect in a single gene with one defective copy of that gene inherited from each parent. The disease occurs when harmful quantities of gangliosides accumulate in the nerve cells of the brain, eventually leading to the premature death of those cells. There is currently no cure or treatment. Tay- Sachs disease is a rare disease. Other autosomal disorders such as cystic fibrosis and sickle cell anemia are far more common. TSD is an autosomal recessive genetic disorder, meaning that when both parents are carriers, there is a 25% risk of giving birth to an affected child.

Bardet Biedl Syndrome (BBS) is an infrequent ciliopathic autosomal recessive genetic disorder that produces many effects and affects various body systems. Consanguineous marriage is conventionally considered as the most frequent etiology. The primary characteristics of the disorder are gradual visual impairment caused by retinal abnormalities, excessive weight gain, learning disabilities, Postaxial Polydactyly, Hypogonadism in males, renal abnormalities (kidney malformations and/or malfunctions). It affects both males and females. There is currently no specific cure for BBS but children with BBS benefit greatly from therapies like physical, occupational, speech and vision services. We, here, have presented a young boy of 15 years with the features of Bardet Biedl Syndrome.

Storage Disorders

Gaucher's Disease (GD) is an autosomal recessive systemic lysosomal storage disorder which is characterized by glucocerebroside deposition in cells of the macrophage-monocyte system as a result of a deficiency in lysosomal P-glycosidase (glucocerebrosidase). GD is a rare genetic disorder. It is the most common amongst the lysosomal storage disorders. GD has been categorised into three types based on the presence of central nervous involvement1. Type 1 is a non-neuronopathic form that presents in childhood or early adulthood. Type 2 is acute neuronopathic form that presents in childhood. It progresses rapidly and is fatal. Type 3 is chronic non-neuronopathic form that presents in childhood but is slowly progressive. Here we describe a case of a three and a half year old male child in whom a diagnosis of Gaucher's disease was made based on bone marrow biopsy and later confirmed by glucocerebrosidase levels estimation.

Autosomal Recessive Pattern

Spinal Muscular Atrophy (SMA) is the second leading genetic disorder inherited in the autosomal recessive pattern due to the absence of the SMN1 gene characterized by loss of motor neurons and progressive muscle wasting, often leading to dependent life and decreased life span. In Ayurveda, this condition can be considered as Kulaja Vyadhi wherein the patient’s Mamsa and Snayu is affected by Vata. This can be regarded as Mamsa-Snayugata Sarvanga Vata. It is said that Prakruta Vata dosha is the life, it is the strength, it is the sustainer of the body, it holds the body and life together. If it is Vikruta it produces Sankocha, Khanja, Kubjatva, Pangutva, Khalli and Soshana of Anga. So, in this disease aggravated Vata does the vitiation of Mamsa and Snayu thus leading to Soshana of both, resulting in Stambha, Nischalikarana of Avayava. A 21years female patient was admitted to our I.P.D with c/o of reduced strength in all four limbs leading to the inability to walk and to maintain erect posture during standing and sitting positions. Based on Ayurvedic principles the patient was initially subjected to Avaranahara Chikitsa followed by Brimhana line of management.

Laurence Moon Bardet Biedle syndrome is a rare, autosomal recessive genetic disorder involving multiple systems and has wide spectrum of clinical features. Characteristic features of this disorder are retinitis pigmentosa, polydactyly, truncal obesity and learning difficulties. It may also be associated with hypogonadism in male and complex genitourinary abnormalities in female. We present a case of 33 years male patient having obesity, decreased vision, polydactyly, hypogonadism and retinitis pigmentosa. These clinical features are consistent with Laurence Moon Bardet Biedle syndrome.Medicine Today 2018 Vol.30(1): 41-43

Life Threatening

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening medical condition characterized by hyperphagocytosis secondary to an inappropriate over-activation of macrophages and lymphocytes that driven by excessive cytokines production which resulted in cellular destructions. It can arise de novo as a result of an autosomal recessive genetic disorder, or in the background of an infection, malignancy or autoimmune disease. Dengue fever is one of the uncommon causes of infection related secondary HLH. Here, we present a case of a Dengue associated HLH which was successfully treated with intravenous methylprednisolone and immunoglobulin G. In conclusion, the purpose of this case report is to illustrate the importance of early recognition and prompt initiation of the appropriate treatment for HLH suspected patient whom otherwise has high mortality rate.
