Pericentric inversion in human chromosome 1 and the risk for male sterility.
A pericentric inversion in chromosome 1 of a severely oligospermic human male is reported. Pachytene analysis in microspread preparations shows an absence of full loop formation in the inversion bivalent and only the rare occurrence of a partial loop. The majority of cells exhibit extensive asynapsis across the inverted segment, or a normal looking synaptonemal complex indicative of heterologou...
متن کاملGoldenhar Syndrome and Pericentric Inversion of Chromosome 9

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%.

متن کاملPrenatal Diagnosis in Pericentric Inversion 6
A four-year-old girl, the proband along with her mother in her subsequent pregnancy was referred to the genetic clinic for evaluation of global developmental delay with a normal karyotype study. On evaluation, dysmorphic features prompted to repeat the karyotype assessment. An unbalanced pericentric inversion of chromosome 6 in the index child was noticed.

متن کاملConstitutional pericentric inversion of chromosome 9 and chronic myeloid leukemia
In the present study, we screened the bone marrow chromosome database entries between March, 2004 and December, 2013 to identify cases with inv(9) along with t(9;22) variations. Our study recorded 2300 cases of confirmed CML (Ph positive), of which only 12 (0.52%) cases had inv(9) and t(9;22). The association between inv(9) and t(9;22) is not fully explored. Therefore more number of cases is re...
متن کاملFamilial pericentric inversion (10) and its effect on two offspring.
A pericentric inversion (10)(p15q24) was observed in three generations of a family. One daughter of the inversion carrier was found to have the inv(10) and trisomy 18. The other offspring had a recombinant (10) chromosome.
