The present study examined performance differences for blacks and whites on 14 separate measures of short-term memory. Using a nationally srratzfied (gendel: race, age, SES, region, and community size) population proportionate sampling plan, 168 black and 983 white children and adolescents (ages 5 years to 19 years) were tested. Age corrected deviation scaled scores (mean of 10 and SD of 3) were calculated at 1 year intervals using the method of rolling weighted averages. In sharp contrast to typical findings with intellectual and most other aptitude measures, only one significant diSference occurred across race on any of the 14 measures of memory. 0 1997 National Academy of Neuropsychology 1. a lack of equivalence of testing conditions, 2. functional inequivalence across groups, and 3. linguistic inequivalence.

This condition is characterized by distinctive facial features, small head size (microcephaly), intellectual disability or learning problems, and behavioral problems. Many affected children have the characteristic features of autism, a developmental condition that affects communication and social interaction. Malformations of the heart, lungs, kidneys, gastrointestinal tract, and genitalia are also common. Infants with Smith-Lemli-Opitz syndrome have weak muscle tone (hypotonia), experience feeding difficulties, and tend to grow more slowly than other infants. Most affected individuals have fused second and third toes (syndactyly), and some have extra fingers or toes (polydactyly).

A review of the literature disclosed fifty-five previously published cases. Both boys and girls can be affected. The syndrome includes bilateral femoral hypoplasia; facial dysmorphism with a cleft palate, micrognathia, a long philtrum, a thin upper lip, and a short broad-tipped nose; dysplasia of the hips; and hypoplasia of the fibulae. Other malformations may be found, including skeletal defects and visceral (especially cardiovascular and genitourinary) abnormalities. Etiopathogenesis of this syndrome remains unknown. Some investigators have suggested a link between the FH-UFS and caudal dysplasia in infants born to diabetic mothers.

MDS is caused by visible deletion or microdeletion of 17p13.3 with haploinsufficiency of LIS1. Typical facial features include a prominent forehead, bitemporal hollowing, short nose with upturned nares, prominent upper lip with downturned vermillion border, low-set posteriorly rotated ears, and micrognathia. Most patients with MDS are suffered from epilepsy and severe developmental delay. Congenital heart diseases are frequently associated with MDS. Kidney anomalies, sacral dimple, omphalocele, genital anomalies, and clinodactyly are also associated with MDS.
