A female infant presented at birth with hypotonia, growth retardation, distinctive facies, multiple congenital anomalies, and a high-pitched mewing cry characteristic of cri du chat syndrome. Chromosome studies from both peripheral blood and fibroblasts showed a 46,XX,5p- karyotype. Parental chromosome studies revealed that the mother carried an apparently balanced pericentric inversion of one chromosome no. 5, 46,XX,inv(5)(p14q35). Meiotic crossing-over in the mother within the inverted segment of chromosome 5 gave rise to the unbalanced karyotype, 46,XX,rec(5)dup q, inv(5)(p14q35)mat in the infant. A small terminal segment of the long arm of chromosome 5 (q35-pter) is duplicated with a deletion of the short arm of chromosome 5 (p14-pter), accounting for the features of cri du chat syndrome. Fewer than 1 in 200 of cri du chat syndrome cases are due to recombination aneusomy arising from a parental inversion of chromosome 5. Some of these cases, however, do not have typical cri du chat syndrome, reflecting significant duplication of 5q material. These cases are reviewed with the present case, and recombination behaviour leading to chromosome imbalance is discussed.

A male infant with karyotype 46,XY,rec(5),dup q,inv(5)(p15.1 q35.1)pat is presented. The proband showed growth and developmental retardation, complex cardiovascular abnormalities, inguinal hernia and microcephaly in addition to facial appearance and cat-like cry characteristic of the cri-du-chat syndrome. Growth and developmental retardation, and microcephaly noted in this patient were markedly more serious than those observed in patients either with partial monosomy 5p or with partial trisomy 5q alone.

A male infant is described in whom congenital anomalies were recognized prenatally by ultrasound examination. The infant was delivered following spontaneous labor and died approximately 15 min after birth. An autopsy revealed major anomalies in the central nervous system (holoprosencephaly with premaxillary agenesis), the gastrointestinal system (esophageal atresia) and the heart (tetralogy of Fallot). Chromosomal studies revealed recombinant chromosome 5 [46,XY, rec(5), dup q, inv(5)(p15q32)], resulting in partial trisomy 5q and partial monosomy 5p. Cytogenetic investigation of the family revealed a pericentric inversion of chromosome 5 in the father and paternal grandmother, 46,XY (and XX, respectively,) inv(5)(p15q32). The congenital anomalies in this infant are more extensive and severe than previously reported in cases of recombination aneusomy involving chromosome 5.

A family is described in which the mother's 9 pregnancies ended in the birth of 2 healthy girls, 4 spontaneous abortions and 3 infants with multiple congenital malformations as bird-headed appearance, pre- and postnatal growth deficiency, microcephaly, micrognathia with small mouth and cat-like cry. Two of the three affected sibs had complex cardiac malformations incompatible with life; the third had a bicuspid aortic valve. Chromosomal investigation revealed an abnormal karyotype: 46,XX,rec(5),dupq,inv(5)(p151q333)pat, leading to a partial monosomy 5p and partial trisomy 5q. A large pericentric inversion of chromosome 5 was found in the father: 46,XY,inv(5)(p151q333) as well as in the firstborn healthy female sib. The clinical features partly fit the partial monosomy 5p as well as the partial trisomy 5q syndrome.

A male infant with partial monosomy 5p and partial trisomy 5q due to paternal pericentric inversion of chromosome 5 (46,XY,rec(5), dup q,inv(5)(p15.1q35.1)pat) is reported together with the oral findings. The phenotype was chiefly the cri-du-chat syndrome. Severe retardation of mental and motor development, microencephaly, cardiac malformation, crying and facial appearance unique to the cri-du-chat syndrome were observed. Perioral and intraoral findings included thin upper lip, down-turning corners of mouth, micrognathia, shallow palate, and cleft of soft palate. Anterior deciduous teeth were small and canine deciduous teeth were conic. The row of deciduous teeth showed a flat arch-like shape that was very wide but short in length. No abnormality was noted in the number of deciduous teeth or the timing of eruption.
