Not para-, not peri-, but centric inversion of chromosome 12.

Goldenhar Syndrome and Pericentric Inversion of Chromosome 9

Oculo-auriculovertebral dysplasia (Goldenhar) is a congenital syndrome. Its phenotype differs from craniofacial anomalies to cardiac, vertebral or central nervous system defects. This syndrome is rare and its etiology is not apparent yet. Pericentric inversion of chromosome 9 is one of the most common structural balanced chromosomal aberrations with its incidences 15% to 25%. Herein we present ...

46,Xinv(Yp+q-) in four generations of an Indian family.

Pericentric inversion of the human Y chromosome has been reported infrequently but it is known to be an inherited anomaly. Several individuals with such an inversion had concomitant karyotypic irregularities, amongst which trisomy 21, gonosome mosaicism, and the 47,XXY karyotype were common (Sparkes, Muller, and Veomett, 1970). This led to speculation that inversion of the Y chromosome signalle...

Chromosome polymorphisms in natural populations of the South American grasshopper Sinipta dalmani

Six populations of Sinipta dalmani from the provinces of Buenos Aires and Entre Rios (Argentina) were analyzed. The populations of “El Palmar” National Park (Entre Rios) were polymorphic for pericentric inversions in pairs M4 and M7 and for a centric fusion involving pair M5 and the X chromosome. The M4 inversion remained similar over time and the karyomorphic frequencies did not depart from th...

Cytogenetics, cytotaxonomy and chromosomal evolution of Chrysomelinae revisited (Coleoptera, Chrysomelidae) *

Nearly 260 taxa and chromosomal races of subfamily Chrysomelinae have been chromosomally analyzed showing a wide range of diploid numbers from 2n = 12 to 2n = 50, and four types of male sex-chromosome systems. with the parachute-like ones Xy(p) and XY(p) clearly prevailing (79.0%), but with the XO well represented too (19.75%). The modal haploid number for chrysomelines is n = 12 (34.2%) althou...
