ABSTRACT

Meckel-Gruber syndrome (MGS) is a rare and lethal autosomal recessive disorder characterized by occipital encephalocele, postaxial polydactyly and bilateral dysplastic cystic kidneys. It can be associated with many other congenital malformations. The incidence of Meckel-Gruber syndrome ranges between 1 in 13,000 to 4,00,000 live births. Antenatal ultrasound examination establishes the diagnosis by identifying at least two of the major features. A case is presented that describes a baby with ambiguous genitalia, who presented with the triad of Meckel-Gruber syndrome. The baby died shortly after birth.

ABSTRACT

Papillon–Lefevre Syndrome(PLS) is a very rare syndrome of autosomal recessive inheritance characterised by palmar plantar hyperkeratosis and early onset of a severe destructive periodontitis, leading to premature loss of both primary and permanent dentitions. The palmar plantar keratoderma typically has its onset between the ages of 1 and 4 years and severe periodontitis starts at the age of 3 or 4 years. The exact pathogenesis of these clinical events remains mainly speculative. An early diagnosis of the syndrome can help preserve the teeth by early institution of treatment, using a multidisciplinary approach. We report a case of 17-year- old female patient with PLS.

ABSTRACT

Hereditary hemochromatosis is an autosomal recessive disorder that disrupts the body’s regulation of iron. It is the most common genetic disease in whites. Men have a 24-fold increased rate of iron-overload disease compared with women. Persons who are homozygous for the HFE gene mutation C282Y comprise 85 to 90 percent of phenotypically affected persons. End-organ damage or clinical manifestations of hereditary hemochromatosis occur in approximately 10 percent of persons homozygous for C282Y. Symptoms of hereditary hemochromatosis are nonspecific and typically absent in the early stages. If present, symptoms may include weakness, lethargy, arthralgias, and impotence. Later manifestations include arthralgias, osteoporosis, cirrhosis, hepatocellular cancer, cardiomyopathy, dysrhythmia, diabetes mellitus, and hypogonadism. Diagnosis requires confirmation of increased serum ferritin levels and transferrin saturation, with or without symptoms. Subtyping is based on genotypic expression. Serum ferritin measurement is the most useful prognostic indicator of disease severity. Liver biopsy is performed to stage the degree of fibrosis with severe ferritin elevation or transaminitis, or to diagnose nonclassical hereditary hemochromatosis in patients with other genetic defects. Treatment of hereditary hemochromatosis requires phlebotomy, and the frequency is guided by serial measurements of serum ferritin levels and transferrin saturation. Iron avidity can result from overtreatment. If iron avidity is not suspected, it may mimic undertreatment with persistently elevated transferrin saturation. Dietary modification is generally unnecessary. Universal screening for hereditary hemochromatosis is not recommended, but testing should be performed in first-degree relatives of patients with classical HFE-related hemochromatosis, those with evidence of active liver disease, and patients with abnormal iron study results. Screening for hepatocellular carcinoma is reserved for those with hereditary hemochromatosis and cirrhosis.

ABSTRACT

Lamellar ichthyosis is an inherited autosomal recessive disorder characterized by non-bullous erythroderma and scaling at birth. We report a patient born encased in a collodion membrane, who later developed generalized, brownish, plate-like scales, anhidrotic skin, scarring alopecia, bilateral ectropion, with a family history of similar-looking skin condition. Skin biopsy demonstrated marked lamellated orthohyperkeratosis and areas of hypergranulosis. Therapeutic trial of four topical agents (extravirgin coconut oil, urea lotion, mineral oil and petroleum jelly) was done which gave minimal improvement of scaling and dryness. Oral retinoids (Acitretin) was then initiated and yielded better results.

ABSTRACT

Homocystinuria is an inborn error on the pathway of the methionine metabolism. It is mainly caused by a cystathionine B-synthase deficiency in the brain or liver. Homocystinuria is biochemically characterized by: 1) an increase of the homocystine and methionine concentration in the plasma; and 2) a decrease of the cystine with an increased excretion of homocystine in the urine. The clinical manifestations of this autosomal recessive disorder include: ectopoia lentis, skeletal abnormalities, high incidence of thromboembolism and high frequency of mental retardation. We have been experiencing a case of a 10 year old female patient who has suffered from homocystinuria. She has undergone mental retardation, poor vision caused by ocular complications and Marfanoid feautures.
