Summary
STAT1 gain-of-function mutations cause immunodeficiency and chronic candidiasis. This study highlights chronic demodicosis as an under-recognized manifestation of this genetic disorder.
Area of Science:
- Immunology
- Genetics
- Dermatology
Background:
- Heterozygous STAT1 gain-of-function (GOF) mutations are the primary genetic cause of chronic mucocutaneous candidiasis (CMC).
- STAT1-GOF mutations lead to combined immunodeficiency, affecting the body's ability to fight infections.
Observation:
- A family with a STAT1-GOF mutation presented with chronic demodicosis.
- Clinical manifestations included facial papulopustular eruptions, blepharitis, and chalazion.
Findings:
- Demodicosis, a skin mite infestation, has rarely been associated with STAT1-GOF mutations.
- This case series suggests a potential link between STAT1-GOF and severe or chronic demodicosis.
Implications:
- Chronic demodicosis may be an under-recognized symptom of STAT1-GOF related immune dysregulation.
- Increased awareness can aid in earlier diagnosis and management of STAT1-GOF in patients with persistent demodicosis.
- Further research is warranted to elucidate the mechanisms connecting STAT1-GOF and demodicosis.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
