Living with Distal trisomy 6q

A rare chromosome condition with slow growth, delayed development, intellectual disability, and distinct facial features.

Understanding Distal trisomy 6q

Distal trisomy 6q is a rare condition caused by an extra piece of the long arm of chromosome 6.

The condition varies a lot. It often involves slow growth, delayed development, and intellectual disability. Facial features can include a small head and small lower jaw, and some people have a short, webbed neck and tight joints. Heart, urinary and genital, eye, hand, and foot differences have been reported, along with umbilical hernia, stiff muscles, and seizures. Signs begin during pregnancy or in the newborn period.

Signs & symptoms

GARD doesn't list specific symptoms for this condition separately, but the summary describes these features:

  • Slow growth
  • Delays in development
  • Intellectual disability
  • Small head size (microcephaly)
  • Short, webbed neck
  • Tight joints (contractures)

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

Diagnosis

    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 genetic specialists.

  3. Ask which tests can help

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