Sorry, no etymologies found.


  • Some rarer genetic conditions, such as hemophilia, fragile X syndrome, and Duchenne muscular dystrophy, are passed to children in a slightly different way, known as X-linked inheritance.

    Our Bodies, Ourselves: Pregnancy and Birth

  • However, in individuals with X-linked lymphoproliferative syndrome (XLP), the immune system does not always respond as it should to specific challenges.

    X-linked Lymphoproliferative Syndrome

  • Therefore, when a male has an alteration in SH2D1A, he will develop clinical signs of X-linked lymphoproliferative syndrome (XLP).

    X-linked Lymphoproliferative Syndrome

  • There are several ways that X-linked lymphoproliferative syndrome (XLP) can be diagnosed.

    X-linked Lymphoproliferative Syndrome

  • Provided that the male partner of a female carrier does not himself have X-linked lymphoproliferative syndrome (XLP), a female child inheriting the alteration will also be a carrier like her mother and not show symptoms of X-linked lymphoproliferative syndrome (XLP).

    X-linked Lymphoproliferative Syndrome

  • However, in some cases, boys or young men with X-linked lymphoproliferative syndrome (XLP) can develop lymphoma without ever having had Epstein-Barr virus (EBV) infection.

    X-linked Lymphoproliferative Syndrome

  • A blood sample is obtained from a male who has clinical symptoms of X-linked lymphoproliferative syndrome (XLP) or from a female who wants to see if she is a carrier of an SH2D1A alteration.

    X-linked Lymphoproliferative Syndrome

  • This child would not be a carrier of X-linked lymphoproliferative syndrome (XLP) and therefore, she could not pass the SH2D1A alteration to her future children.

    X-linked Lymphoproliferative Syndrome

  • This suggests that other genes besides SH2D1A could be responsible for causing certain cases of X-linked lymphoproliferative syndrome (XLP).

    X-linked Lymphoproliferative Syndrome

  • This information could strengthen the conclusion that the SH2D1A alteration was linked to the diagnosis of X-linked lymphoproliferative syndrome (XLP) or XLP carrier state in the individual being tested.
