Pattern of chromosomal anomalies detected in children with suspected genetic disorders

, , and

REZUMAT

Objectives: to analyze the types of chromosomal abnormalities in patients suspected of genetic disease and to estimate the frequency of chromosome aberrations detected in selected children and the comparison of the obtained results with other similar studies.

Material and methods: chromosome analysis was performed on 592 patients of pediatric age, selected in the Clinical Genetics Department of IOMC „Prof. Dr. Alfred Rusescu” during an interval of 4 years, 2007-2010, using as selection criteria the following features: pre/postnatal growth retardation, facial dysmorphism, multiple congenital anomalies, mental retardation.

Results: various types of chromosomal aberrations had been identified; out of the 321 cases diagnosed with some chromosomal anomalies, 285 cases (88.79%) had numerical anomalies, trisomy 21 representing the most common genetic abnormality, followed by Patau and Edwards syndromes, and 36 cases (11,21%) had structural chromosomal anomalies.

Conclusions: cytogenetic analysis is useful for investigation of children with genetic diseases of unknown cause in order to confirm the clinical diagnosis and provide genetic counseling.

Key words: cytogenetics, chromosomal syndromes, autosomes, gonosomes, diagnosis, genetic counseling

REZUMAT

Obiective: analiza tipurilor de anomalii cromozomiale la pacienţii suspectaţi de boli genetice, estimarea frecvenţei aberaţiilor cromozomiale detectate la copiii selectaţi şi compararea acestor cifre cu alte studii similare. Material şi metode: analiza cromozomială a fost efectuată pe 592 de pacienţi de vârstă pediatrică, selectaţi în cadrul cabinetului de genetică al IOMC „Prof. Dr. Alfred Rusescu“ într-un interval de 4 ani, 2007-2010, având drept criterii de selecţie următoarele aspecte fenotipice: retard de creştere pre/postnatal, dismorfisme faciale, anomalii congenitale multiple, retard mental. Rezultate: s-au evidenţiat numeroase tipuri de anomalii cromozomiale; dintre cei 321 de pacienţi diagnosticaţi cu anomalii cromozomiale, 285 de cazuri (88,79%) au prezentat anomalii cromozomiale numerice, trisomia 21 reprezentând cea mai frecventă anomalie cromozomială, urmată de sindrom Patau şi sindrom Edwards, iar 36 cazuri (11,21%) au fost identificate cu diverse anomalii cromozomiale structurale. Concluzii: analiza citogenetică este utilă pentru investigarea copiilor cu boli genetice de cauză necunoscută în vederea confirmării diagnosticului clinic şi acordării sfatului genetic.
