What is Adenylosuccinate lyase deficiency?

What is Adenylosuccinate lyase deficiency?

Adenylosuccinate lyase deficiency is a neurological disorder that causes brain dysfunction (encephalopathy) leading to delayed development of mental and movement abilities (psychomotor delay), autistic behaviors that affect communication and social interaction, and seizures.

What is Asld?

Adenylosuccinate lyase deficiency (ASLD) is a rare, inherited metabolic disorder caused by a genetic change which lowers the effectiveness of the enzyme adenylosuccinate lyase (ASL).

What is ADSL Gene?

The ADSL gene provides instructions for making an enzyme called adenylosuccinate lyase. This enzyme performs two steps in the process that produces (synthesizes) purine nucleotides. These nucleotides are building blocks of DNA, its chemical cousin RNA, and molecules such as ATP that serve as energy sources in the cell.

How do you get Adermatoglyphia?

Adermatoglyphia is inherited in an autosomal dominant pattern , which means one copy of the altered SMARCAD1 gene in each cell is sufficient to cause the condition. In many cases, an affected person has one parent with the condition.

What is autism Succinylpurinemic?

Succinylpurinemic autism: increased sensitivity of defective adenylosuccinate lyase towards 4-hydroxy-2-nonenal.

What is ASL deficiency?

Defect: Argininosuccinate Lyase (ASL) Deficiency, also known as Argininosuccinic Aciduria (AA), is the result of a mutated or deficient argininosuccinate lyase enzyme. This defective or deficient enzyme leads to inadequate ureagenesis, accumulation of argininosuccinic acid, and deficient endogenous arginine production.

What is ADSL deficiency?

Adenylosuccinate lyase (ADSL) deficiency is a defect of purine metabolism affecting purinosome assembly and reducing metabolite fluxes through purine de novo synthesis and purine nucleotide recycling pathways. The disorder shows a wide spectrum of symptoms from slowly to rapidly progressing forms.

Is there treatment for adermatoglyphia?

Adermatoglyphia is caused by changes ( mutations ) in the SMARCAD1 gene and is inherited in an autosomal dominant manner. Treatment is typically only necessary if other features are present.

Can you be born without fingerprint?

A genetic mutation causes people to be born without fingerprints, a new study says. Almost every person is born with fingerprints, and everyone’s are unique. But people with a rare disease known as adermatoglyphia do not have fingerprints from birth.

How is Argininosuccinase deficiency treated?

Intravenous benzoate, arginine, and phenylacetate administration may be indicated as initial therapy for hyperammonemia, but such combined therapy is appropriate only prior to specific diagnosis. Hemodialysis, if available, reduces the blood ammonia levels more efficiently and quickly.

What do you need to know about adenylosuccinate lyase deficiency?

General Discussion. Adenylosuccinate lyase deficiency (ASLD) is a rare, inherited metabolic disorder due to a lack of the enzyme adenylosuccinate lyase (ASL).

What causes adenylosuccinase deficiency in the human body?

Adenylosuccinate lyase deficiency occurs when the ADSL gene is not working correctly. [2] [3] DNA changes known as pathogenic variants are responsible for making genes work incorrectly or sometimes, not at all. Adenylosuccinase deficiency is inherited in an autosomal recessive pattern. [3]

What are the side effects of ADSL deficiency?

Difficulty eating and drinking due to the issues described above (secondary feeding problems) Weakness in the trunk of the body (axial hypotonia) with increased strength and muscle mass in the limbs (peripheral hypertonia). This only occurs in severe ADSL deficiency.
