ABSTRACT
Catel-Manzke syndrome, also known as micrognathia-digital-syndrome, is a rare autosomal recessive disorder characterized by the combination of the two cardinal features Pierre-Robin sequence and bilateral hyperphalangy leading to ulnar clinodactyly (ulnar curvature of the phalanges) and radial deviation (radial angulation at the metacarpophalangeal joint) of the index fingers. Individuals without one of these major hallmarks or with additional hand malformations have been described as atypical or Catel-Manzke-like syndrome. Biallelic TGDS pathogenic variants have thus far been detected in eight individuals with typical Catel-Manzke syndrome and in one fetus with additional features. Here we report on two individuals with TGDS pathogenic variants who presented with mild radial deviation and ulnar clinodactyly of the index fingers but without radiologic signs of hyperphalangy. Furthermore, both individuals have disproportionate short stature, a feature that has not yet been associated with Catel-Manzke syndrome. Our data broaden the phenotypic spectrum of TGDS-associated Catel-Manzke syndrome and expand the indication for diagnostic testing.
