Living with Alport syndrome-intellectual disability-midface hypoplasia-elliptocytosis syndrome

A rare X-linked condition from a missing piece of DNA, with kidney disease, intellectual disability, facial differences, and a blood cell shape problem.

Understanding Alport syndrome-intellectual disability-midface hypoplasia-elliptocytosis syndrome

Alport syndrome-intellectual disability-midface hypoplasia-elliptocytosis syndrome is a rare condition that combines kidney, facial, learning, and blood features.

It is a type of constitutional hemolytic anemia, in which red blood cells break down early. It combines Alport syndrome, an underdeveloped middle of the face, intellectual disability, and oval-shaped red blood cells (elliptocytosis). It comes from a missing piece of DNA on the X chromosome. It starts during pregnancy, at birth, or in infancy.

Signs & symptoms

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

  • Severe intellectual disability
  • Oval-shaped red blood cells (elliptocytosis)
  • Kidney disease (glomerulopathy)
  • Flat nasal bridge
  • Downward-slanting eyes
  • Hair differences

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 blood and bone marrow specialists, brain and nervous system specialists, genetic specialists and kidney specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

Quick facts

Symptoms usually startduring Pregnancy, at Birth, and as an Infant
InheritanceX-Linked

GARD says it is caused by a contiguous gene deletion, a missing piece of the X chromosome (Xq22.3) that takes out several genes, including COL4A5, FACL4, and AMMECR1. It is inherited in an X-linked way.
