Is Shwachman Diamond Syndrome contagious?

Shwachman-Diamond Syndrome is not contagious, meaning it cannot be spread from person to person through touch, air, or bodily fluids. It is a rare, inherited genetic condition, and there is absolutely no risk to others when interacting with or living alongside someone diagnosed with Shwachman-Diamond Syndrome.

What causes Shwachman-Diamond Syndrome?

Shwachman-Diamond Syndrome is a multisystem genetic disorder, primarily caused by mutations in the SBDS gene. Because it is genetic, it is present from birth; it is not caused by viruses, bacteria, or environmental pathogens. In the DiseaseMaps.org community, 14 members have shared their experiences with this condition, highlighting that it is a lifelong, inherited journey rather than an infectious disease.

Why is there confusion about contagion?

Because individuals with Shwachman-Diamond Syndrome often experience frequent infections due to neutropenia (a low count of certain white blood cells), some may mistakenly associate their illness with an infectious process. However, the immune deficiency in Shwachman-Diamond Syndrome is an internal, non-communicable biological vulnerability, not an infection that can be transmitted to others. Stigma often arises from a lack of public awareness regarding genetic versus infectious health conditions.

Is Shwachman-Diamond Syndrome hereditary?

Yes, Shwachman-Diamond Syndrome follows an autosomal recessive inheritance pattern. This means that for a child to be born with the condition, they must inherit one mutated copy of the SBDS gene from each carrier parent. Key characteristics include:

• Exocrine pancreatic insufficiency (impaired digestion).


• Bone marrow dysfunction, often leading to neutropenia.


• Skeletal abnormalities and short stature.


• Increased risk of developing myelodysplastic syndrome (MDS) or leukemia.
