D-bifunctional protein deficiency, an autosomal recessive peroxisomal disorder, is caused by mutations in the HSD17B4 gene, leading to severe outcomes.
Peroxisomal Bifunctional Enzyme Deficiency, also known as D-bifunctional protein deficiency, is an autosomal recessive disorder involving mutations in the HSD17B4 gene, leading to severe neurological and metabolic consequences.
Definition and Overview
Peroxisomal Bifunctional Enzyme Deficiency, also known as D-bifunctional protein deficiency, is an autosomal recessive disorder affecting fatty acid metabolism in peroxisomes.
Peroxisomal Bifunctional Enzyme Deficiency is inherited in an autosomal recessive manner, meaning both parents must pass on a mutated copy of the HSD17B4 gene for the condition to manifest.
Mutations in the HSD17B4 Gene
The development of Peroxisomal Bifunctional Enzyme Deficiency is associated with genetic mutations in the HSD17B4 gene, which encodes the D-bifunctional protein crucial for peroxisomal fatty acid oxidation processes.
