Novel pericentric inversion inv(9)(p23q22.3) in unrelated individuals with fertility problems in the Southeast European population. J Hum Genet 2020; 65:783-795.

Abstract
Pericentric inversions are among the known polymorphisms detected in the general population at a frequency of 1-2%. Despite their generally benign nature, pericentric inversions affect the reproductive potential of carriers by increasing the risk for unbalanced live-born offspring, miscarriages, or other fertility problems. Here we present a novel large pericentric inversion of chromosome 9, inv(9)(p23q22.3), detected in 30 heterozygote carriers, 24 from seven apparently unrelated families and 6 isolated patients, where the probands were mainly referred for fertility and prenatal problems. The inversion carries a significant risk for recombinant abnormal chromosomes, as in two families one supernumerary rec(9)dup(9p) and one rec(9)dup(9q) were identified, leading to neonatal death and miscarriage, respectively. The inversion carriers were identified by three different laboratories in Greece, Cyprus and Germany respectively, however all carriers have Southeast European origin. The inversion appears to be more frequent in the Greek population, as the majority of the carriers were identified in Greece. We were able to determine that the inversion is identical in all individuals included in the study by applying a combination of several methodologies, such as karyotype, fluorescence in situ hybridization (FISH), chromosomal microarrays (CMA) and haplotype analysis. In addition, haplotype analysis supports that the present inversion is identical by descent (IBD) inherited from a single common ancestor. Our results are, therefore, highly indicative of a founder effect of this inversion, presumably reflecting an event that was present in a small number of individuals that migrated to the current Southeast Europe/Northern Greece from a larger population.

Abstract
Pericentric inversions of chromosome 9 leading to unbalanced live-born offspring are relatively rare and so far only four cases have been reported. Here we present two sisters with an unbalanced recombinant chromosome 9 which resulted from a large maternal pericentric inversion inv(9)(p24.3q34.1). Further molecular characterisation of the aberrant chromosome 9 by 250k SNP array analysis showed a terminal 460 kb loss of 9p24.3 and a terminal 8.9 Mb gain of 9q34.11. We compared the clinical features of these two patients with the previous reported four cases as well as with patients with similar sized 9pter deletions or 9qter duplications. Based upon this study, we suggest that the recombinant chromosome 9 phenotype is mainly the result of duplication of a 3.4 Mb region of chromosome 9q34.11q34.13.

Abstract
Chromosomal abnormalities are the major contributor to the genetic risks of infertility treatment associated with intracytoplasmic sperm injection (ICSI). The study objective was to assess prospectively the frequency of chromosomal aberrations in couples undergoing ICSI. A total of 2650 infertile couples (5300 patients) underwent chromosome analysis before undergoing ICSI in the Egyptian IVF-ET Centre. Heparinized blood samples were cultured, harvested and banded according to standard methods. Overall, 96.94% of the patients studied (5138/5300) had a normal karyotype, while the remaining 162 patients (3.06%) had an abnormal karyotype. Male patients constituted the majority of abnormalities; 138 males (85.19%) and 24 females (14.81%). These chromosomal aberrations included 117 cases (2.2%) of sex chromosome abnormalities; 113 males and four females. Forty-five patients (0.85%) had autosomal aberrations; 25 of them were males and 20 were females. The current data show that chromosomal abnormalities affect 3.06% of infertile patients, and occur in both sexes, but more predominantly in males undergoing ICSI for male factor infertility. It is recommended that chromosomal analysis be performed before undergoing ICSI, to identify patients who can be offered preimplantation genetic diagnosis.

Abstract
Only nine non-polymorphic constitutional pericentric inversions of chromosome 9 have been described. We report on a familial inv(9)(p24q13) associated with sterility in three brothers. The mother's chromosomes were normal in blood lymphocytes (n=130); the father was already deceased and his karyotype unknown. However, the presence of any of the maternal chromosomes 9 (as assessed by C-banding) in her carrier children is inconsistent with the assumption of maternal mosaicism. Two single sisters were also carriers. The same rearranged chromosome 9 in the three sterile brothers can hardly be regarded as a fortuitous association, especially when the breakpoints are almost identical to those of the sole inversion previously found in an azoospermic male. If their father was a carrier, the observed sterility may be the result of 'chromosome anticipation', a phenomenon already invoked for certain familial chromosomal rearrangements.

Abstract
A male infant with distal 9q trisomy syndrome associated with an unusual inheritance of ABO blood type is reported. His clinical features were concordant with those of distal 9q trisomy syndrome. His karyotype was 46,XY, -10, +der (10) t(9;10) (q22.3;q24.3) confirmed by G-banding and high resolution methods. His father had the balanced translocation t(9;10) (q22.3;924.3). He had a blood type of AB, despite his father's blood type of AB and his mother's blood type of O. The gene of ABO blood type is located at 9q34.1-q34.2. Therefore, he would have received A and B type alleles from his father. 9q trisomy syndrome should be carefully investigated with ABO blood type.
