Description : THis gene encodes the mitochondrial enzyme which is catalyzes the rate-limiting step in heme (iron-protoporphyrin) biosynthesis. The enzyme encoded by tHis gene is the housekeeping enzyme; a separate gene encodes a form of the enzyme that is specific for erythroid tissue. The level of the mature encoded protein is regulated by heme: high levels of heme down-regulate the mature enzyme in mitochondria while low heme levels up-regulate. A pseudogene of tHis gene is located on chromosome 12. Alternative splicing results in multiple transcript variants encoding different isoforms.

However, these compounds and their potential use as therapeutic agents require further research and development.

How is ALAS1 expression regulated? 11/20/2021

ALAS1 expression is regulated at multiple levels, including transcriptional control by factors like erythroid transcription factors and the heme-regulated eIF2α kinase. It can also be modulated post-transcriptionally, such as by feedback inhibition by heme.

Can ALAS1 deficiency improve over time? 09/08/2021

The severity of ALAS1 deficiency usually remains fairly stable over time. Some individuals may experience fluctuating symptoms due to factors like infections or stress. However, without proper treatment and management, the condition typically progresses and can lead to long-term complications. Regular medical care and monitoring are essential to address symptoms and prevent complications.

Is ALAS1 deficiency inherited? 09/01/2021

Yes, ALAS1 deficiency is inherited in an autosomal recessive manner. This means that both parents must carry a copy of the mutated ALAS1 gene for their child to be affected. Carriers of a single mutated gene are usually asymptomatic but have a 50% chance of passing the mutated gene to each of their children, who would then need to inherit a second mutated gene from the other parent to develop the condition.

What are the symptoms of ALAS1 deficiency or dysregulation? 08/01/2021

The symptoms of ALAS1 deficiency or dysregulation can vary depending on the specific underlying condition. However, symptoms may include anemia (low red blood cell count), fatigue, pale skin, shortness of breath, weakness, and other complications related to impaired heme production.

Can ALAS1 deficiency be treated? 03/26/2021

Currently, there is no specific cure for ALAS1 deficiency. However, the treatment primarily focuses on managing the symptoms and complications associated with the condition. This may involve blood transfusions to address anemia, iron chelation therapy to reduce iron overload, and supportive care to manage other symptoms. It is important to consult with a healthcare professional for personalized treatment recommendations.

Can ALAS1 deficiency be detected prenatally? 09/13/2020

Yes, prenatal diagnosis is possible for ALAS1 deficiency through genetic testing. If there is a known family history of the condition or if both parents are carriers, prenatal testing can be performed using techniques such as chorionic villus sampling (CVS) or amniocentesis to analyze the fetal DNA for ALAS1 gene mutations. However, it is essential to consult with a genetic counselor or healthcare professional to understand the benefits, limitations, and potential risks of prenatal testing.

How does ALAS1 deficiency lead to X-linked sideroblastic anemia? 12/04/2019

X-linked sideroblastic anemia is caused by mutations in the ALAS2 gene, which is responsible for expressing a different isoform of 5'-aminolevulinate synthase (ALAS2) in erythroid cells. However, ALAS1 deficiency can also contribute to sideroblastic anemia if it affects heme production in non-erythroid cells.

Can ALAS1 deficiency be prevented? 04/26/2019

Since ALAS1 deficiency is a genetic disorder, it cannot be entirely prevented. However, genetic counseling and carrier testing can be helpful for individuals with a family history of ALAS1 deficiency.
