Abstract (croatian)
Cilj: Prstenasti ili ring kromosom rijetka je strukturna promjena kromosoma koja najčešće nastaje zbog terminalne delecije na oba kraka kromosoma te ponovnog spajanja preostalih dijelova kratkog i dugog kraka kromosoma u prstenastu strukturu. Sindromi prstenastih kromosoma iznimno su rijetki s incidencijom od 1 : 50.000 živorođene djece. U ovom radu prikazujemo prvi slučaj djevojčice sa sindromom prstenastog kromosoma 18 zabilježenog na Zavodu za biologiju i medicinsku genetiku (Medicinski fakultet, Sveučilište u Rijeci). Prikaz slučaja: Bolesnica je dvanaestogodišnja djevojčica sa psihomotornom retardacijom, mikrocefalijom, niskim rastom, dismorfijom lica (hipertelorizam, hipoplazija srednjeg lica, usni kutovi okrenuti prema dolje, rascjep nepca, prognatija, nisko postavljene uške), obostranom stenozom vanjskog slušnog hodnika uz provodnu gluhoću i brahidaktilijom. Citogenetičkom analizom utvrđen je mozaični kariotip: 46,XX,r(18)(p11.3;q23)[97]/45,XX,-18[3] de novo. Daljnjom kliničkom obradom utvrđeno je kako bolesnica ima obilježja klasična za deleciju oba kraka 18. kromosoma. Klinička obilježja djeteta prikazana su i uspoređena s klasičnim kliničkim obilježjima sindroma. Rasprava i zaključak: Iako je sindrom prstenastog kromosoma 18 rijedak genetički poremećaj, nužno je prepoznati dijete s multiplim prirođenim anomalijama već na razini primarne zdravstvene zaštite te ga zbog pravilnog genetičkog informiranja i odabira odgovarajuće terapije što prije uputiti na specijalističku obradu, kao i na citogenetičku analizu.
Abstract (english)
Aim: Ring chromosomes are rare structural chromosomal aberrations which form after the breakage in both terminal regions of the affected chromosome with fusion of the short and long arm into a ring formation. The incidence of ring chromosome syndromes is estimated to be about 1:50.000 live born children. Here we present the first case of a girl with ring chromosome 18 syndrome identifed at the Department of biology and medical genetics (School of medicine, University of Rijeka). Case report: The patient is a twelve-year old girl with psychomotor retardation, microcephaly, short stature, dysmorphic facies (hypertelorism, midface hypoplasia, downturned corners of mouth, cleft palate, prognathia, low-set ears), bilateral stenosis of the external auditory canal with conductive deafness and brachydactyly. Cytogenetic analysis determined a mosaic karyotype: 46,XX,r(18)(p11.3;q23)[97]/45,XX,-18[3] de novo. Our patient has the characteristic features of 18p and 18q deletion syndromes. We present the clinical features of the patient and compare them to the classical features of 18p and 18q deletion syndromes. Discussion and conclusion: Although ring chromosome 18 syndrome is a rare genetic disorder it is necessary to identify the child with multiple congenital anomalies by primary care physicians and refer the child to the proper medical instituti on for genetic testing and genetic counseling.
