We present a case of Wiedemann -
Rautenstrauch syndrome -extremely rare syndrome associated with neonatal
progeria. At birth progeroid appearance was noted with large head, triangular
face, deep set eyes, small nose and two natal teeth. During 15 years of
observation progeroid appearance of face remained almost unchanged. She is
severly mentally and physically retarded, have no palpable adipose tissue
except of caudal region. Premature senility prompted us to examine some
parametes of cellular senescence. So far telomere lenght was examined in
fibroblasts from patients with two other syndromes associated with progeria:
Werner syndrome and Hutchinson-Gilford syndrome. We performed analysis of
terminal restriction fragment (TRF) lenght as a measure of telomere lenght.
Mean TRF lenght was 13.5 kb of our patient fibroblasts which is not shortened
when compared to the normal fibroblasts. From our results it seems that the
replicative lifespan of fibroblasts in culture does not correlate with donor
age.
