Nearly 50 variants in TERC congenifa been associated with idiopathic pulmonary fibrosis, aplastic anemia, interstitial pneumonia, dissqueratosis dyskeratosis congenita. Walne et al [] reported a family with two affected sibs, in one of whom a TINF2 pathogenic variant was identified the other was deceased and could not be tested ; neither parent had the pathogenic variant, suggesting germline mosaicism in a parent.

Dyskerin plays multiple roles in human cells. All of their daughters who will be heterozygotes carriers and will usually not be affected. There is also an increased risk for solid tumors, typically squamous cell carcinoma of head and neck or anogenital cancer.
