Living with Multiple congenital anomalies due to 14q32.2 maternally expressed gene defect

A rare genetic condition (Kagami-Ogata syndrome) with excess fluid in pregnancy, a larger size at birth, chest and belly wall differences, and developmental delay.

Understanding Multiple congenital anomalies due to 14q32.2 maternally expressed gene defect

Multiple congenital anomalies due to 14q32.2 maternally expressed gene defect, also called Kagami-Ogata syndrome, is a rare genetic condition that starts before birth.

Features include extra amniotic fluid (polyhydramnios) linked with a large placenta, larger size at birth, belly wall defects, and a bell-shaped chest with coat-hanger-looking ribs. Babies may have feeding and swallowing difficulties, certain facial features, developmental delay, and intellectual disability. There is a higher chance of a liver tumor called hepatoblastoma. Signs are seen during pregnancy, at birth, or in infancy.

Signs & symptoms

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

  • Bell-shaped chest and coat-hanger ribs
  • Larger than usual size at birth
  • Feeding difficulties
  • Delays in reaching developmental milestones
  • Intellectual disability
  • Gap between the belly muscles (diastasis recti)

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 brain and nervous system specialists and genetic 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
InheritanceAutosomal Dominant

Changes in genes (also called variants) in the 14q32.2 region cause this condition. GARD lists autosomal dominant inheritance, and refers to a defect in a maternally expressed gene.
