Children's Health Care, February 2015. (Abstract) 2014. Comprehensive review article about BTHS. Ferreira C, Thompson WR, Vernon H. Barth syndrome. GeneReviews. October 9, 2014. (PubMed - OpenAccess) Moderate CL deficiency associated with milder BTHS phenotype Bartter syndrome is also characterized by low levels of potassium in the blood (hypokalemia), which can result in muscle weakness, cramping, and fatigue. Rarely, affected children develop hearing loss caused by abnormalities in the inner ear (sensorineural deafness) The purpose of this overview is to increase clinician awareness of the genetic basis of dilated cardiomyopathy (DCM) and the benefits of early diagnosis and management to individuals with genetic DCM

Signs and symptoms can vary among affected individuals, even within the same family. The major features include: Progressive vision loss due to deterioration of the retina

Barth syndrome Genetic and Rare Diseases Information

Objectives: Barth syndrome is an ultra-rare, infantile-onset, X-linked recessive mitochondrial disorder, primarily affecting males, due to variants in TAZ encoding for the cardiolipin transacylase tafazzin Barth syndrome is a relatively rare but serious genetic condition that usually affects boys and men. As of 2017, the best estimate is that it occurs in 1 in 300,000 U.S. births. Barth syndrome usually causes abnormalities with the heart, immune system, muscles, and growth Barth syndrome (BTHS) is an X-linked genetic disorder. The disorder, which affects multiple body systems, is diagnosed almost exclusively in males. It is named after Dutch pediatric neurologist Peter Barth Barth syndrome (BTHS) is an X-linked disease caused by mutations in the TAZ gene. More than 160 mutations in the TAZ gene have been linked to this disease. It is a rare disease, found in 1 out of every 300,000 to 400,000 live births, though it is widely known that the disease is underdiagnosed

In Joubert syndrome with oral-facial-digital features (JS-OFD), oral findings can include midline upper-lip cleft, midline groove of tongue, hamartomas of the alveolar ridge and cleft palate
  4. History. Barth syndrome was first described by Barth et al in 1983.3 The title of the original article was An X-linked mitochondrial disease affecting cardiac muscle, skeletal muscle and neutrophil leucocytes.3 Elevated levels of organic acids, particularly 3-methylglutaconic acid (3-MGA), in the serum and urine were first reported in 1996 by Christodoulou et al.5 The protein that is.

  6. Barth syndrome is manifested in a variety of ways at birth. A majority of BTHS patients are hypotonic at birth, show signs of cardiomyopathy within the first few months of life, and experience a deceleration in growth in the first year, despite adequate nutrition. As patients progress into childhood, their height and weight lag significantly.

Barth syndrome (BTHS, OMIM 302060) is a rare X-linked disorder with a prevalence of approximately 1 in 1,000,000 males. 1 BTHS is clinically characterized by cardiac left ventricular noncompaction. This report describes Barth syndrome, which is a subtype of 3-methylglutaconic aciduria; Barth syndrome is inherited in an X-linked recessive pattern. The human gene implicated in this disease is TAZ, which encodes tafazzin, an inner mitochondrial membrane protein necessary for cardiolipin remodeling

Clinical characteristics: Barth syndrome is characterized in affected males by cardiomyopathy, neutropenia, skeletal myopathy, prepubertal growth delay, and distinctive facial gestalt (most evident in infancy); not all features may be present in a given affected male. Cardiomyopathy, which is almost always present before age five years, is typically dilated cardiomyopathy with or without.

Barth syndrome is a clinical association of myocardial dysfunction, neutropenia, skeletal myopathy, abnormal mitochondria, organic aciduria (primarily 3-methylglutaconic aciduria), growth retardation, and cholesterol abnormalities. 52 It is an X-linked disorder and has been thought to be allelic to several phenotypically different disorders on. Barth syndrome can also lead to elevations of branched-chain amino acid intermediates, resulting in elevated C5-OH on NBS or plasma acylcarnitine analysis. The last group of disorders leads to secondary elevations of 3-methylglutaconic acid, which can also result in elevated C5-OH Barth syndrome is an X-linked recessive disorder due to mutations of the TAZ gene that result in abnormal mitochondrial cardiolipin metabolism. 1 Although most commonly characterized by early-onset cardiomyopathy, 2 patients with Barth syndrome also often have neutropenia, delayed growth, and muscle weakness. 3 We report the history of a boy followed for 10 years with idiopathic neutropenia.

The geneticist and the genetic counselor bring up the possibility of Barth syndrome and recommend preliminary plasma amino acids and urine organic acids to be ordered. As a hospitalist you look at GeneReviews before ordering the samples to be collected and see that a preliminary diagnosis of Barth syndrome can be made through genetic testing of.
