WebNov 13, 2024 · Characterizing Dyskeratosis Congenita Caused By Parn Mutations in the Zebrafish. Inherited bone marrow failure syndromes (IBMFs) are a group of rare genetic disorders characterized by deficient hematopoiesis and extra-hematologic traits. Most known entities are related to a specific gene or group of genes, but others still remain unclassified. WebPresumably, PARN mutations destabilize hTR levels ( 10) and lead to reduced telomerase activity through a haploinsufficiency mechanism similar to dyskerin ( DKC1) mutations ( 11 ); further investigation will be needed to determine whether PARN plays other roles in telomere biology.
