Definition
  1. Noun:
    • X-linked severe combined immunodeficiency: A specific, inherited form of Severe Combined Immunodeficiency (SCID) that primarily affects male children. It results from a mutation in a gene located on the X chromosome. This gene normally codes for a protein essential for the proper development and function of T cells and other immune cells.
Usage Examples
  • Noun:
    • The infant was diagnosed with X-linked SCID, requiring immediate isolation and treatment.
    • Early detection of X-linked SCID through newborn screening can be life-saving.
    • The research focuses on gene therapy for X-linked SCID.
Advanced Usage
  • Medical Context: The term is used almost exclusively in clinical, genetic, and research contexts to specify this particular genetic etiology of SCID.
    • The study compared outcomes for patients with X-linked SCID versus other forms of the disorder.
Variants and Related Words
  • SCID (noun): Severe Combined Immunodeficiency, the broader category of disorders.
  • X-SCID (noun): A common abbreviated form for X-linked SCID.
  • ADA-SCID (noun): Another form of SCID caused by adenosine deaminase deficiency, often contrasted with X-linked SCID.
Synonyms
  • X-linked severe combined immunodeficiency (noun): The full medical term.
  • X-SCID (noun): The standard abbreviation.
Notes on Meaning

This term refers specifically to a medical condition with a known genetic cause (an X-linked mutation). It is not a general term for immune deficiency but names a precise diagnosis. The definition highlights the mechanism: the mutated gene prevents T cells from developing a functional receptor for a crucial growth factor.

Noun
  1. SCID in male children resulting from mutation of a gene that codes for a protein on the surface of T cells that allows them to develop a growth factor receptor
