Abstract
A 14‐year‐old severely retarded male with deletion of chromosomal band 7 cen → q112 is described. Clinical features include short stature, microcephaly, unusual facies with narrow forehead, short nose, malar hypoplasia, protruding alveolar ridges and incisors, receding chin, relatively long philtrum, and large ears. In addition, he had bilateral inguinal herniae cryptorchidism with hypogonadism, pulmonic stenosis, and spastic quadriplegia. Normal activity of beta‐glucuronidase was found in the patient's leukocytes. This finding suggests that the gene is not in the deleted region, narrowing the smallest region of overlap to 7q112 → q22.
