Abstract
Maleness associated with a 45,X karyotype is a rare condition in childhood. It is usually diagnosed in adult age because of infertility. We report a unique case of an unbalanced translocation t(Y;21) in a 14-year-old boy with 45,X karyotype referred because of short stature, thin habitus and puberty delay. Hormone analysis showed low serum levels of basal testosterone, insulin-like growth factor (IGF-I) and gonadotrophins. Diagnosis of GH deficiency and puberty delay were made. He was treated with human chorionic gonadotropin (hCG) and GH therapy, respectively, for 6 and 24 months.

Abstract
Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported. In particular, only three individuals has been described with a Y;21 translocation, up to now. We report on an additional case of an infertile man in whom a Y;21 translocation was associated with the deletion of a large part of the Y chromosome long arm. Applying various techniques, including conventional cytogenetic procedures, fluorescence in situ hybridisation (FISH) analysis and array comparative genomic hybridization (array-CGH) studies, we identified a derivative chromosome originating from a fragment of the short arm of the chromosome Y translocated on the short arm of the 21 chromosome. The Y chromosome structural rearrangement resulted in the intactness of the entire short arm, including the sex-determining region Y (SRY) and the short stature homeobox (SHOX) loci, although translocated on the 21 chromosome, and the loss of a large part of the long arm of the Y chromosome, including azoospermia factor-a (AZFa), AZFb, AZFc and Yq heterochromatin regions. This is the first case in which a (Yp;21p) translocation has been ascertained using an array-CGH approach, thus reporting details of such a rearrangement at higher resolution.

Abstract
PURPOSE Patients with a karyotype of 45,X (monosomy X) normally display a female phenotype. However, in some rare cases, monosomy X is associated with maleness. Here we describe a case of a male with a 45,X karyotype and primary infertility, which prompted molecular investigation of the sex-determination gene SRY. METHODS Karyotyping was performed by GTG-banded chromosome analysis. The presence and location of SRY was investigated using PCR and FISH, respectively. RESULTS PCR confirmed the presence of the SRY gene while FISH analysis demonstrated its location on the p arm of chromosome 13. These findings demonstrate that autosomal retention of SRY can be sub-microscopic and emphasize the importance of PCR and FISH in the genetic workup of the monosomic X male.

Abstract
OBJECTIVE To describe the molecular and cytogenetic characterization of a de novo unbalanced Y;autosome translocation in a 45,X mentally retarded male. DESIGN Descriptive case study and literature review. SETTING Tertiary medical center. PATIENT(S) A 17-year-old 45,X mentally retarded male with no stigmata of Turner syndrome. INTERVENTION(S) Molecular and cytogenetic investigations, physical examination, and hormonal assays. MAIN OUTCOME MEASURE(S) Cytogenetic analysis, fluorescence in situ hybridization (FISH), array comparative genomic hybridization (CGH), and polymorphic DNA marker analysis. RESULT(S) The FISH showed a Y/18p translocation. Array CGH revealed a loss of distal chromosome 18p material and a loss of part of Yq material corresponding to deletions of chromosomal segments of 18pter-->18p11.2 and Yq11.221-->Yqter. Polymorphic DNA markers analysis showed that the X chromosome was of maternal origin and the deletion of 18p was of paternal origin. CONCLUSION(S) This study confirms the usefulness of array CGH in the detection of subtle chromosomal rearrangements resulting in an unbalanced Y;autosome translocation.

Abstract
OBJECTIVE To conduct clinicopathologic and cytogenomic diagnostics of an infertile male with a karyotype of 45,X. DESIGN Case report. SETTING Research laboratory at a university hospital. PATIENT(S) A male with a karyotype of 45,X was diagnosed because of infertility, and his parents also were examined. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Cytogenomics studies were performed by multiple polymerase chain reaction and fluorescent in situ hybridization. RESULT(S) Testicular pathology results showed Sertoli cell-only syndrome, and the SC nodule tissue was diagnosed as angiolipomata. Thus, the patient's karyotype was reinterpreted to be 45,X,der(Y)t(Y;13)(q11.2;q12),-13.ish der(Y)(SRY+, DYZ3+, wcp13+). Analysis of DNA polymorphism showed that the chromosome X was of maternal origin. CONCLUSION(S) This is the first case reported with a 45,X,der(Y)t(Y;13)(q11.1;q12),-13, which will be useful for the infertility phenotype-molecular karyotype correlation.

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
A boy with signs of Klinefelter syndrome, mild facial dysmorphic features, and severely retarded speech development displayed a female karyotype with mosaicism for two marker chromosomes 48,XX,+mar1,+mar2[68]/47,XX,+mar1[19]/47,XX,+mar2[6]/46,XX[8]. Using chromosomal microdissection, locus-specific fluorescence in situ hybridization (FISH), and PCR with several Y-chromosome markers, the larger supernumerary marker chromosome (SMC) was characterized as a ring Y-chromosome. Detection of the SRY-region explained the male phenotype. The smaller second marker chromosome contained the pericentromeric region of chromosome 8. We suggest that the co-occurrence of a partial Y-chromosome and partial trisomy 8 explain the severe speech delay and the facial dysmorphic features.

Abstract
Translocations between the Y chromosome and an autosome are rare. We report a phenotypic male with a translocation between the Y chromosome and chromosome 6p, leading to partial 6p monosomy and XX male syndrome. He is the second child to be reported with this karyotype. Phenotypic findings included growth retardation, severe developmental delay, a Dandy-Walker malformation, cardiac and urogenital abnormalities, bilateral hearing loss, cleft palate, severe kyphoscoliosis, minor digital anomalies, and a hypoplastic phallus. Craniofacial dysmorphism consisted of dolichocephaly, hypertelorism, down-slanting palpebral fissures, depressed nasal bridge and a tented upper lip. Cytogenetic analysis showed the karyotype 46,XX,der(6)t(Y;6)(p11.2;p23).ish der(6)(SRY+,6pTEL48-). The effects of partial monosomy 6p are discussed and compared to other patients with interstitial and terminal 6p deletions.

Abstract
An unbalanced Y;autosome translocation leading to a male with a 45,X karyotype is rare with about 30 published cases. A male with a 45,X karyotype as a result of a unique, submicroscopic, unbalanced Y;16 translocation is presented with alpha-thalassemia/mental retardation syndrome.
