A rare maternal disease-related embryofetopathy with characteristics of variable developmental anomalies of the fetus due to teratogenic effect of elevated maternal body temperature (resulting from febrile illness or hot environment exposure). Reported developmental anomalies include neural tube defects (spina bifida, encephalocele, anencephaly), cardiac defects (transposition of great vessels), urogenital defects (hypospadias), abdominal wall defects, cleft lip/palate, eye defects (cataract, coloboma) or various minor anomalies (for example bifid uvula, preauricular pit or tag). Consensus regarding cause and effect relationship has not been reached. [from
