We report on an Arabic sibship originating from Morocco in which four children manifest an undiagnosed sublethal multiple congenital anomaly/mental retardation (MCA/MR) syndrome of intrauterine growth retardation (IUGR), microcephaly, large soft pinnae, telecanthus or true hypertelorism with squint, flat face, unusual hooked nose, very narrow mouth, retrognathia, and extremely severe neurologic impairment. One child was stillborn. Three others died in a cachectic state during their second year. One child had a severe cerebral malformation compatible with semilobar holoprosencephaly. Other inconstant manifestations are anterior chamber cleavage defect, preaxial polydactyly of feet, interventricular septal defect, and atresia of the external auditory meatus. Autosomal recessive inheritance is likely.

D008607	Intellectual Disability	Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range.

D008831	Microcephaly	A congenital abnormality in which the CEREBRUM is underdeveloped, the fontanels close prematurely, and, as a result, the head is small. (Desk Reference for Neuroscience, 2nd ed.)

D005804	Genes, Lethal	Genes whose loss of function or gain of function MUTATION leads to the death of the carrier prior to maturity. They may be essential genes (GENES, ESSENTIAL) required for viability, or genes which cause a block of function of an essential gene at a time when the essential gene function is required for viability.
