Location of CD40L mutations in XHIM patients. The schematic
representation of the cDNA sequence and of the domains of the CD40L
molecule is according to Seyama et al. (17). IC,
intracellular tail; TM, transmembrane domain; ECU, extracellular unique
region; TNFH, tumor necrosis factor-homology domain. For each exon and
domain, the starting nucleotide or amino acid residue number is
indicated. Nonsense mutations are shown above the scheme, insertions
(ins) and deletions (del) below.
