Partial trisomy of the short arm of chromosome 3 (3p25 to 3pter). A distinct clinical entity. 1979

C Parloir, and J P Fryns, and H Van den Berghe

Two profoundly mentally retarded brothers with partial trisomy for the distal part of the short arm of chromosome 3 (3p25 to 3pter) are described. Their anomaly arose as a segregation product of a balanced t(3p-;18q+) translocation in the mother. Compared with the other cases of partial 3p trisomy reported up to now, the present patients display a similar craniofacial dysmorphism with hypertelorism, broad nasal tip, short upper lip with prominent philtrum, and a large mouth with down-turned corners. Other stigmata, such as a prominent, high forehead with frontal bossing and full cheeks, were present during childhood but progressively disappeared.

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.
