AD, autosomal dominant; AR, autosomal recessive; DKC1, dyskerin; PARN, poly(A)-specific ribonuclease; RTEL1, regulator of telomere elongation helicase 1; TERC, telomerase RNA component; TERT, telomerase reverse transcriptase; TINF2, TRF1-interacting nuclear factor 2; XLR, X-linked recessive.
P values of age at baseline TL, age at most recent TL, length of follow-up, and sex were all >.05.
RTEL1 is AD inheritance in 1 treated and 1 untreated patient, and AR in 1 treated patient.
