Aase-Smith syndrome; Hypoplastic anemia - triphalangeal thumbs, Aase-Smith type; Diamond-Blackfan with AS-II

What are the causes of Aase Syndrome?

Many cases of Aase syndrome occur without a known reason and are not passed down through families (inherited). However, some cases (45%) have been shown to be inherited. These are due to a change in 1 of 20 genes important for making protein correctly (the genes make ribosomal proteins).

This condition is similar to Diamond-Blackfan anemia, and the two conditions should considered the same. A missing piece on chromosome 19 is found in some people with Diamond-Blackfan anemia.

The anemia in Aase syndrome is caused by poor development of the bone marrow, which is where blood cells are formed.

What are the symptoms of Aase Syndrome?

Symptoms may include:

  • Absent or small knuckles
  • Cleft palate
  • Deformed ears
  • Droopy eyelids
  • Inability to fully extend the joints from birth
  • Narrow shoulders
  • Pale skin
  • Triple-jointed thumbs

What are the current treatments for Aase Syndrome?

Treatment may involve blood transfusions in the first year of life to treat anemia.

A steroid medicine called prednisone has also been used to treat anemia associated with Aase syndrome. However, it should only be used after reviewing the benefits and risks with a provider who has experience treating anemias.

A bone marrow transplant may be necessary if other treatment fails.

What is the outlook (prognosis) for Aase Syndrome?

The anemia tends to improve with age.

What are the possible complications of Aase Syndrome?

Complications related to anemia include:

  • Fatigue
  • Decreased oxygen in the blood
  • Weakness

Heart problems can lead to a variety of complications, depending on the specific defect.

Severe cases of Aase syndrome have been associated with stillbirth or early death.

How do I prevent Aase Syndrome?

Genetic counseling is recommended if you have a family history of this syndrome and wish to become pregnant.

What are the latest Aase Syndrome Clinical Trials?
A Phase II Study of Olaparib in Patients With Advanced Biliary Tract Cancer With Aberrant DNA Repair Gene Mutations

Summary: This phase II trial studies how well olaparib works in treating patients with biliary tract cancer that has spread to other places in the body (metastatic) and with aberrant DNA repair gene mutations. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Etiologic Investigation of Cancer Susceptibility in Inherited Bone Marrow Failure Syndromes: A Natural History Study

Background: A prospective cohort of Inherited Bone Marrow Failure Syndrome (IBMFS) will provide new information regarding cancer rates and types in these disorders. Pathogenic variant(s) in IBMFS genes are relevant to carcinogenesis in sporadic cancers. Patients with IBMFS who develop cancer differ in their genetic and/or environmental features from patients with IBMFS who do not develop cancer. These cancer-...
