“Pseudomosaicism” for 4p – in amniotic fluid cell culture proven to be true mosaicism after birth

Abstract excerpt

Pseudomosaicism is noted in approximately 1% of amniotic fluid cell studies. Some represent numerical abnormalities, but pseudomosaicism for structural chromosomal abnormalities is also seen. Pseudomosaicism is not usually considered clinically significant. Recently, we evaluated a 13-month-old girl with developmental delay and minor anomalies suggestive of 4p- syndrome. In 5 of 100 peripheral lymphocytes, she...
