摘要: Analysis of clinical and cytogenetic findings taken from 62 published cases partial trisomies chromosome 13 showed that 15 had trisomy for the proximal long arm 47 distal arm. Persistence fetal haemoglobin (Hb F), increased projections polymorphonuclear leucocytes (PMN), depressed nasal bridge, cleft lip/palate, clinodactyly were more frequent in patients with 13. In group, common features included haemangioma, bushy eyebrows, curled eyelashes, prominent philtrum, thin upper lip, highly arched palate, hexadactyly. addition, several other to both groups, often showing inconsistency even when same segment was trisomy. The influence second aneusomy as most likely cause such inconsistent overlapping phenotypes is discussed view fact 42 derived a balanced translocation carrier parent.
