A – Transmissible paternal/maternal genetic alterations:  Diseases that affect a single gene or monogenic (dominant, recessive or X-linked), whose mutation is known and can be analysed.  X chromosome-linked disorders, whose gene is not known or has some heterogeneity, but is avoided with sex selection.  Structural chromosomal abnormalities such as Robertsonian or reciprocal translocations. B...

Test code: OP1201 The Blueprint Genetics Congenital Stationary Night Blindness Panel is a 17 gene test for genetic diagnostics of patients with clinical suspicion of congenital stationary night blindness. The panel covers genes associated with autosomal recessive, autosomal dominant and X-linked forms of congenital stationary night blindness (CSNB). The clinical utility of this diagnostic panel...

Wiskott-Aldrich syndrome (WAS) is a life-threatening X-linked recessive immunodeficiency disease described as a clinical triad of thrombocytopenia, eczema, and recurrent infections, caused by mutations of the WAS protein (WASP) gene. The milder form of this disease is X-linked thrombocytopenia (XLT) that presents only as platelet abnormalities. Mutation analysis for 15 boys with Wiskott-Aldrich...

Dyskeratosis congenita (DC) is a rare inherited disorder with most families being of the X linked recessive type. We describe three families which show linkage to the marker DXS52 on Xq28. The combined maximum lod score was 2.00 at zero recombination. This is further evidence that the X linked DC gene is located at Xq28 and brings the reported maximum lod score for DC and DXS52 to 5.33 at zero ...

The most common of the primary immunodeficiency diseases are those that involve inadequate antibody production. The characteristic presentation of these disorders is recurrent sinopulmonary infections. An arrest in B cell development at the pre-B cell stage leads to agammaglobulinemia and an insignificant number of B cells. X-linked agammaglobulinemia is the most common of these developmental a...
