A child with hypoplasia of the cerebellum and brainstem in association with an unbalanced translocation, resulting in a partial deletion of the short arm of chromosome 5 and a partial trisomy of the short arm of chromosome 10, is described. A balanced translocation was present in his mother and maternal grandmother. A maternal uncle had died at the age of 4 years with the same clinical picture. After reviewing the literature, we conclude that the monosomy 5p is the most likely cause for this malformation. We suggest that the possible existence of chromosomal anomalies should always be considered in the differential diagnosis of hypoplasia of the cerebellum and/or brainstem.

D002531 Cerebellum The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills. Cerebella,Corpus Cerebelli,Parencephalon,Cerebellums,Parencephalons

It is caused by a deletion of the short arm of chromosome 5 (5p-). 5p Deletion Syndrome,Chromosome 5p- Syndrome,5p Minus Syndrome,5p- Syndrome,Cat Cry Syndrome,Chromosome 5 Short Arm Deletion Syndrome,Chromosome 5p Deletion Syndrome,Crying Cat Syndrome,Deletion of Short Arm of Chromosome 5 Syndrome,5p Deletion Syndromes,5p Minus Syndromes,5p Syndrome,5p- Syndrome, Chromosome,5p- Syndromes,5p- Syndromes, Chromosome,Cat Cry Syndromes,Chromosome 5p- Syndromes,Cri du Chat Syndrome,Cri-du-Chat Syndromes,Crying Cat Syndromes,Deletion Syndrome, 5p,Deletion Syndromes, 5p,Minus Syndrome, 5p,Minus Syndromes, 5p,Syndrome, 5p Deletion,Syndrome, 5p Minus,Syndrome, 5p-,Syndrome, Cat Cry,Syndrome, Chromosome 5p-,Syndrome, Cri-du-Chat,Syndrome, Crying Cat,Syndromes, 5p Deletion,Syndromes, 5p Minus,Syndromes, Cat Cry,Syndromes, Chromosome 5p-,Syndromes, Cri-du-Chat,Syndromes, Crying Cat
D004314 Down Syndrome A chromosome disorder associated either with an extra CHROMOSOME 21 or an effective TRISOMY for chromosome 21. Clinical manifestations include HYPOTONIA, short stature, BRACHYCEPHALY, upslanting palpebral fissures, epicanthus, Brushfield spots on the iris, protruding tongue, small ears, short, broad hands, fifth finger clinodactyly, single transverse palmar crease, and moderate to severe INTELLECTUAL DISABILITY. Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE.
