A girl with a new de novo translocation of 4q onto the short arm of acrocentric 22 is reported as a case of "pure" partial trisomy 4q. Her karyotype was 46, XX,-22, +mar, t(4;22)(q25-->qter;p11) identified by Giemsa staining and FISH. Comparison of the proband with previously reported cases of "pure" partial trisomy 4q showed the main clinical features to be growth retardation, psychomotor retardation, microcephaly, large, low set, malformed ears, prominent nasal bridge, ptosis and epicanthus.

PMID:"Pure" partial trisomy 4q25-qter owing to a de novo 4;22 translocation. 873 Feb 95

We describe an 8-years old female with supernumerary chromosome der(21)t(4;21)(q25;q22) resulting in partial trisomy 4q25-qter and partial trisomy 21(pter-q22). The extra material was originated from a reciprocal balanced translocation carrier mother (4q;21q). Karyotyping was confirmed by FISH using whole chromosome painting probes for 4 and 21q and using 21q22.13-q22.2 specific probe to rule out trisomy of Down syndrome critical region. Phenotypic and cytogenetic findings were compared with previously published cases of partial trisomy 4q and 21q. Our patient had the major criteria of distal trisomy 4q namely severe psychomotor retardation, growth retardation, microcephaly, hearing impairment, specific facies (broad nasal root, hypertelorism, ptosis, narrow palpebral fissures, long eye lashes, long philtrum, carp like mouth and malformed ears) and thumbs and minor feet anomalies. In spite of detection of most of the 3 copies of chromosome 21, specific features of Down syndrome (DS) were lacked in this patient, except for notable bilateral symmetrical calcification of basal ganglia. This report represents further delineation of the phenotype-genotype correlation of trisomy 4q syndrome. It also supports that DS phenotype is closely linked to 21q22. Nevertheless, presence of basal ganglia calcification in this patient may point out to a more proximal region contributing in its development in DS, or that genes outside the critical region may influence or control manifestations of DS features.
