Figure 2 DNA sequence electropherogram of the patient’s TNFRSF1A exon 4 amplification product, illustrating the heterozygous G→A substitution (indicated by an arrow), which results in the replacement of arginine (CGG), amino acid 92, by glutamine (CAG).

Figure 3 Sequence analysis of TNFRSF1A exon 3 in the affected patient. The electropherogram shows the heterozygous T→G replacement (indicated by an arrow), which leads to the substitution of phenylalanine (TTC) by valine (GTC) at amino acid position 60.

Figure 4 Alignment of amino acid sequences encoded by exon 3 of the TNFRSF1A gene of 5 different species, demonstrating absolute sequence conservation of phenylalanine at position 60 (1, human; 2, mouse [Mus musculus]; 3, rat [Rattus norvegicus]; 4, cat [Felis catus]; 5, pig [Sus scrofa]).

Figure 5 Pedigree of the patient and her family. Open symbols represent healthy individuals, while the solid symbol represents the affected subject. Question marks indicate that these individuals were not available for genotyping (wt, wild-type).
