Summaries for D-Bifunctional Protein Deficiency

Genetics Home Reference : 25 D-bifunctional protein deficiency is a disorder that causes deterioration of nervous system functions (neurodegeneration) beginning in infancy. Newborns with D-bifunctional protein deficiency have weak muscle tone (hypotonia) and seizures. Most babies with this condition never acquire any developmental skills. Some may reach very early developmental milestones such as the ability to follow movement with their eyes or control their head movement, but they experience a gradual loss of these skills (developmental regression) within a few months. As the condition gets worse, affected children develop exaggerated reflexes (hyperreflexia), increased muscle tone (hypertonia), more severe and recurrent seizures (epilepsy), and loss of vision and hearing. Most children with D-bifunctional protein deficiency do not survive past the age of 2. A small number of individuals with this disorder are somewhat less severely affected. They may acquire additional basic skills, such as voluntary hand movements or unsupported sitting, before experiencing developmental regression, and they may survive longer into childhood than more severely affected individuals. Individuals with D-bifunctional protein deficiency may have unusual facial features, including a high forehead, widely spaced eyes (hypertelorism), a lengthened area between the nose and mouth (philtrum), and a high arch of the hard palate at the roof of the mouth. Affected infants may also have an unusually large space between the bones of the skull (fontanelle). An enlarged liver (hepatomegaly) occurs in about half of affected individuals. Because these features are similar to those of another disorder called Zellweger syndrome (part of a group of disorders called the Zellweger spectrum), D-bifunctional protein deficiency is sometimes called pseudo-Zellweger syndrome.

MalaCards based summary : D-Bifunctional Protein Deficiency, also known as bifunctional peroxisomal enzyme deficiency, is related to peroxisomal acyl-coa oxidase deficiency and neonatal adrenoleukodystrophy. An important gene associated with D-Bifunctional Protein Deficiency is HSD17B4 (Hydroxysteroid 17-Beta Dehydrogenase 4), and among its related pathways/superpathways are Primary bile acid biosynthesis and Biosynthesis of unsaturated fatty acids. The drugs chenodeoxycholic acid and Ursodeoxycholic acid have been mentioned in the context of this disorder. Affiliated tissues include liver, bone and eye, and related phenotypes are decreased nerve conduction velocity and cerebral hypoplasia

Disease Ontology : 12 A peroxisomal disease characterized by, in severe cases, infantile-onset of hypotonia, seizures, and abnormal facial features with most dieing before age 2 years that has material basis in homozygous or compound heterozygous mutation in the HSD17B4 gene on chromosome 5q2.

NIH Rare Diseases : 52 D-bifunctional protein deficiency (DBP deficiency) is a genetic disorder that affects the ability of the body to effectively break down fat from our diet. It is typically characterized by hypotonia (low muscle tone) and seizures in the newborn period. Other symptoms include unusual facial features and an enlarged liver (hepatomegaly). Most babies with this condition never gain any developmental skills and do not survive past the age of 2. DBP deficiency is caused by mutations in the HSD17B4 gene and is inherited in an autosomal recessive manner. Some researchers have suggested classifying DBP deficiency into three subtypes, depending on how severely the mutation in the HSD17B4 gene affects the function of the gene and the protein that it codes for. Almost all individuals with types I, II, and III have similar signs and symptoms. A fourth subtype has additionally been proposed for individuals that have less severe symptoms. While there is no cure for DBP deficiency, treatment is focused on improving nutrition and growth, controlling symptoms, and limiting the progression of liver disease.

OMIM : 56 D-bifunctional protein deficiency is a disorder of peroxisomal fatty acid beta-oxidation. See also peroxisomal acyl-CoA oxidase deficiency (264470), caused by mutation in the ACOX1 gene (609751) on chromosome 17q25. The clinical manifestations of these 2 deficiencies are similar to those of disorders of peroxisomal assembly, including X-linked adrenoleukodystrophy (ALD; 300100), Zellweger cerebrohepatorenal syndrome (see 214100) and neonatal adrenoleukodystrophy (NALD; see 601539) (Watkins et al., 1995). DBP deficiency has been classified into 3 subtypes depending upon the deficient enzyme activity. Type I is a deficiency of both 2-enoyl-CoA hydratase and 3-hydroxyacyl-CoA dehydrogenase; type II is a deficiency of hydratase activity alone; and type III is a deficiency of dehydrogenase activity alone. Virtually all patients with types I, II, and III have a severe phenotype characterized by infantile-onset of hypotonia, seizures, and abnormal facial features, and most die before age 2 years. McMillan et al. (2012) proposed a type IV deficiency on the basis of less severe features; these patients have a phenotype reminiscent of Perrault syndrome (PRLTS1; 233400). Pierce et al. (2010) noted that Perrault syndrome and DBP deficiency overlap clinically and suggested that DBP deficiency may be underdiagnosed. (261515)

KEGG : 36 D-bifunctional protein (DBP) deficiency is an autosomal recessive inborn error of peroxisomal fatty acid oxidation. DBP is a homodimeric enzyme with 79-kDa subunits, each of which consists of three functional units. And it catalyzes the second and third steps of peroxisomal beta-oxidation of fatty acids. The biochemical hallmark of this disorder is the accumulation of very long-chain fatty acids (VLCFA), 2-methyl branched-chain fatty acids, and the bile acid intermediates (DHCA/THCA). The clinical presentation is very severe, and most affected children die within the first 2 years of life. Virtually all patients present with neonatal hypotonia and seizures.
