Recently, mutations in the X-linked ubiquitin protease 26 (USP26) gene have been proposed to be associated with male infertility. In particular a 371insACA, 494T>C and 1423C>T haplotype, which results in a T123-124ins, L165S and H475Y amino acid change respectively, has been reported to be associated with Sertoli cell-only syndrome (SCOS) and an absence of(More)
Most patients with pseudohypoparathyroidism type 1b (PHP-1b) display a loss of imprinting (LOI) encompassing the GNAS locus resulting in PTH resistance. In other imprinting disorders, such as Russell-Silver or Beckwith-Wiedemann syndrome, we and others have shown that the LOI is not restricted to one imprinted locus but may affect other imprinted loci for(More)
Despite the heterogeneous clinical presentations, the majority of patients with 22q11.2 deletion syndrome (22q11.2 DS) have either a common recurrent 3 Mb deletion or a less common, 1.5 Mb nested deletion, with breakpoint sites in flanking low-copy repeats (LCR) sequences. Only a small number of atypical deletions have been reported and precisely defined.(More)
By moving essential body fluids and molecules, motile cilia and flagella govern respiratory mucociliary clearance, laterality determination and the transport of gametes and cerebrospinal fluid. Primary ciliary dyskinesia (PCD) is an autosomal recessive disorder frequently caused by non-assembly of dynein arm motors into cilia and flagella axonemes. Before(More)
Both CMV-specific IgG avidity index (AI) and CMV-specific IgM concentration were studied in different stages of CMV infection in both immunocompromised and immunocompetent patients. In these two groups (61 patients), a past CMV infection was associated with a mean AI constantly higher than 80%, just as the secondary infections observed in 18(More)
Cerebral, ocular, dental, auricular, skeletal syndrome (CODAS, OMIM 600373) is a very rare congenital malformation syndrome. This clinical entity is highly distinctive and associates mental retardation, cataract, enamel abnormalities, malformations of the helix, epiphyseal and vertebral malformations, and characteristic dysmorphic features. Since 1991, only(More)
