Hartsfield syndrome

Harstfield syndrome is the rare and unique association of holoprosencephaly (HPE) and ectrodactyly, with or without cleft lip and palate, and variable additional features. HPE and ectrodactyly can occur, separately, as part of numerous syndromes, but the co-occurrence of these two malformations has only been reported only in a very limited number. Additional signs such as craniosynostosis, hypertelorism or hypotelorism, microphthalmia, abnormal ears, radial agenesis, genital anomalies, severe psychomotor retardation, and hypothalamic-pituitary dysfunction have been observed. Dominant or recessive FGFR1 mutations are responsible for Hartsfield syndrome.
