Klinische und molekulargenetische Befunde beim isolierten sporadischen Retraktionssyndrom nach Stilling-Türk-Duane

Abstract

Associated conditions in DURS patients most commonly involve the ear, the spinal column, the kidneys and the heart and the upper limbs. No mutations in SALL4 could be detected in patients with isolated sporadic DURS as opposed to findings in familial Okihiro syndrome. However, Okihiro syndrome shows marked intra- and interfamilial variability, suggesting that in rare cases of isolated DURS a causative SALL4 mutation may be found.
