β¦ Synopsis
A male infant with partial trisomy 1q syndrome (46,XY,der(21),t(1;21)(q25;q22)pat) is described. Clinical findings include small for gestational age, hypoglycemia, ocular hypertelorism, microphthalmia, coloboma of the iris, low-set ears, beak nose, micrognathia, micropenis, cryptorchidism, presacral dimple, flexion contractures of the fingers, bifid thumb, Simian crease, and overriding toes. In addition, he had a large omphalocele not previously seen in trisomy 1q. Postmortem findings include underdeveloped cerebellum, a thymus with moderate depletion of thymocytes, a large PDA, ASD, small adrenal, and fatty change of the liver. The grandfather, father, and a male sibling have translocation t(1;21)(q25;q22). A family history of repeated spontaneous abortions is present.

The clinical features consisting mainly of enophthalmos, beaked nose, narrow palpebral fissures, receding chin, long fingers and toes, typical for chromsomal syndrome or partial trisomy 9q, were confirmed in a new case.
Two unrelated patients with a strikingly similar phenotype (low birth weight and poor thriving; mental retardation; dolichocephaly; beaked nose; deeply set eyes; prominent maxilla and receding small chin; long fingers with a peculiar clench) were partially trisomic for two different segments of 9q.

This communication contributes an additional case of partial trisomy for the long arm of chromosome 4[46,XX,t(X;4)(Q27;Q25)]. Three generations of the patient's family were karyotyped and her mother and brother were found to be balanced translocation carriers. From the patient's clinical examination
