How many people are affected by glutaric acidemia type I ?
Glutaric acidemia type I occurs in approximately 1 of every 30,000 to 40,000 individuals. It is much more common in the Amish community and in the Ojibwa population of Canada, where up to 1 in 300 newborns may be affected.

What are the genetic changes related to glutaric acidemia type I ?
Mutations in the GCDH gene cause glutaric acidemia type I. The GCDH gene provides instructions for making the enzyme glutaryl-CoA dehydrogenase. This enzyme is involved in processing the amino acids lysine, hydroxylysine, and tryptophan. Mutations in the GCDH gene prevent production of the enzyme or result in the pro...

Is glutaric acidemia type I inherited ?
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

What is (are) fatty acid hydroxylase-associated neurodegeneration ?
Fatty acid hydroxylase-associated neurodegeneration (FAHN) is a progressive disorder of the nervous system (neurodegeneration) characterized by problems with movement and vision that begin during childhood or adolescence. Changes in the way a person walks (gait) and frequent falls are usually the first noticeable sign...

What are the genetic changes related to fatty acid hydroxylase-associated neurodegeneration ?
Mutations in the FA2H gene cause FAHN. The FA2H gene provides instructions for making an enzyme called fatty acid 2-hydroxylase. This enzyme modifies fatty acids, which are building blocks used to make fats (lipids). Specifically, fatty acid 2-hydroxylase adds a single oxygen atom to a hydrogen atom at a particular poi...

What is (are) X-linked chondrodysplasia punctata 1 ?
X-linked chondrodysplasia punctata 1 is a disorder of cartilage and bone development that occurs almost exclusively in males. Chondrodysplasia punctata is an abnormality that appears on x-rays as spots (stippling) near the ends of bones and in cartilage. In most infants with X-linked chondrodysplasia punctata 1, this s...

What are the genetic changes related to X-linked chondrodysplasia punctata 1 ?
X-linked chondrodysplasia punctata 1 is caused by genetic changes involving the ARSE gene. This gene provides instructions for making an enzyme called arylsulfatase E. The function of this enzyme is unknown, although it appears to be important for normal skeletal development and is thought to participate in a chemical ...

Is X-linked chondrodysplasia punctata 1 inherited ?
This condition is inherited in an X-linked recessive pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the ARSE gene in each cell is sufficient to cause the condition. In females (who h...

What is (are) familial lipoprotein lipase deficiency ?
Familial lipoprotein lipase deficiency is an inherited condition that disrupts the normal breakdown of fats in the body, resulting in an increase of certain kinds of fats.

What are the genetic changes related to familial lipoprotein lipase deficiency ?
Mutations in the LPL gene cause familial lipoprotein lipase deficiency.
