Description

In 2 unrelated patients with telomere-related bone marrow failure (PFBMFT1; 614742), Yamaguchi et al. (2005) identified heterozygosity for a his412-to-tyr missense mutation (H412Y) in exon 2 of the TERT gene. Telomere length in patient granulocytes was less than 10% of control values, and cell lysates carrying the mutation showed about 50% telomerase activity.

In a Scottish man with autosomal recessive dyskeratosis congenita-4 (DKCB4; see 613989), Du et al. (2008) identified compound heterozygosity for H412Y and P704S (187270.0014). Du et al. (2008) showed that the mutant H412Y protein had 36% residual activity.
