Hyper‑IgM Syndrome (HIGM): (AICDA for HIGM2) (Known Mutation)

Clinical Use

Use

This test is designed for cases where a known mutation in AICDA (associated with Hyper‑IgM Syndrome Type 2) can be documented by the ordering physician. It provides analysis of the specific known mutation site rather than full gene sequencing.

Special Instructions

This option is available when the mutation is known and can be documented by the ordering physician. If the mutation cannot be documented, test 252425 (full gene sequencing) should be ordered. Informed consent for genetic testing (L7832) is a related document.
