What are the signs and symptoms of trisomy 13?

Trisomy 13 is a chromosomal condition associated with severe intellectual disability and physical abnormalities in many parts of the body. Individuals with this condition often have heart defects, brain or spinal cord abnormalities, very small or poorly developed eyes (microphthalmia), extra fingers and/or toes (polydactyly), cleft lip or palate, and decreased muscle tone (hypotonia).[1] Many infants with trisomy 13 fail to grow and gain weight at the expected rate (failure to thrive), have severe feeding difficulties, and episodes in which there is temporary cessation of spontaneous breathing (apnea).[2]
