Case Report A small supernumerary marker chromosome, derived from chromosome 22, possibly associated with repeated spontaneous abortions

open access: yes, 2010
We report a phenotypically normal couple with repeated spontaneous abortions and without other clinical features. Clinical, hematological, biochemical, and endocrinological aspects of the couple did not reveal any abnormalities. The karyotype of the wife

Limited Clinical Impact of Androgen Receptor Repeat Length (CAG and GGC) in Klinefelter Syndrome: A Multivariable Analysis

open access: yesAndrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.

Single-Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum. [PDF]

open access: yesPlant Biotechnol J
ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.

Supernumerary small marker chromosome (SMC) and uniparental disomy 22 in a child with confined placental mosaicism of trisomy 22: Trisomy rescue due to marker chromosome formation

open access: yes, 2003
Trisomy rescue is one of various proposed mechanisms in formation of supernumerary small marker chromosomes (SMC) and uniparental disomy (UPD). In the present report a small de novo marker chromosome derived from chromosome 14 or 22 was diagnosed at ...

A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics

open access: yesAndrology, EarlyView.
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to

The Influence of Parenting Style on Neurocognitive Development of Children With an Extra X or Y Chromosome: A Prospective 1‐Year Follow‐Up Study

open access: yesAndrology, EarlyView.
ABSTRACT Background As sex chromosome trisomies (SCTs), including 47, XXX, 47, XXY, and 47, XYY, are associated with increased risk for neurodevelopmental challenges, studying SCTs may help in understanding the role of early parental caregiving in shaping neurodevelopmental phenotypes of this genetically at‐risk population.

Sleep Disorders in Klinefelter Syndrome and Other Sex Chromosome Aneuploidies: A Narrative Review

open access: yesAndrology, EarlyView.
ABSTRACT Background Sex chromosome aneuploidies (SCAs) are among the most frequent types of chromosomal aneuploidies and include Klinefelter syndrome (47,XXY and higher‐grade variants), 47,XYY syndrome, Turner syndrome (45,X), and trisomy X (47,XXX).

Neoplastic Risk in Patients With Klinefelter Syndrome

open access: yesAndrology, EarlyView.
ABSTRACT Background Besides gonadal involvement (hypogonadism, male factor infertility, and testicular hypotrophy), patients with Klinefelter syndrome (KS) may suffer from several extra‐gonadic complications, including neoplastic events. Objective The aim of this review is to summarize all major clinical evidence dealing with the association between KS
