CHD4-related neurodevelopmental disorder

Definisjon

A rare multiple congenital anomalies/dysmorphic syndrome characterized by developmental delay, speech delay and variable degree of intellectual disability (mostly mid-to-moderate but some patients may also have normal intelligence) due to CHD4 gene mutations. Even though clinical manifestations are significantly variable among patients, most patients manifest dysmorphic facial features (could sometimes include macrocephaly), congenital heart defects, hypotonia and opthalmologic abnormalities. Other clinical features may include brain structure anomalies, skeletal anomalies, hearing impairment and gonadal abnormalities.
