Fig. 1From: Diagnostics of rare disorders: whole-exome sequencing deciphering locus heterogeneity in telomere biology disordersPedigrees of three families with telomere biology disorders. The panel shows pedigrees of patients with telomere biology disorders (TBD). The original index cases are indicated as P1.1-P3. Solid symbols indicate affected patients, open symbols unaffected. For each family, the identified variants in TBD-associated genes are indicated by M. Normal alleles are listed as NBack to article page
