Reticular dysgenesis is a rapidly fatal variant of severe combined immunodeficiency associated with a lack of both myeloid and lymphoid cell precursors, but SCID can arise from a variety of circumstances which se1ectively target lymphoid cell differentiation.[7]
In the ensuing years, differences were noted in inheritance patterns for SCID. This indicated that there was more than one cause for this fatal syndrome characterized by an absence of T cells and all adaptive immunity. In many families there was an X-linked recessive mode of inheritance while in others an autosomal recessive mode of inheritance was observed.
