Living with Combined immunodeficiency due to GINS1 deficiency

A rare inherited immune condition with slow growth before and after birth, low white blood cells and repeated infections.

Understanding Combined immunodeficiency due to GINS1 deficiency

Combined immunodeficiency due to GINS1 deficiency is a rare inherited condition that affects the immune system and growth.

A problem with copying DNA stops some immune cells from maturing in the bone marrow, especially natural killer (NK) cells. People have slow growth before and after birth, low neutrophils (a type of white blood cell), and repeated viral and bacterial infections. Eczema and mild facial differences can also occur. Symptoms are seen during pregnancy and in newborns.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Slow growth before and after birth
  • Short stature
  • Repeated infections
  • Low neutrophil count and no natural killer cells
  • Eczema
  • Small head size (microcephaly)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include allergy and immune system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in GINS1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Immune Deficiency Foundation may keep lists of experts for this condition.

Quick facts

Symptoms usually startduring Pregnancy and as a Newborn
InheritanceAutosomal Recessive
GenesGINS1

Changes in the GINS1 gene are listed. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
