Acromelic dysplasias: similarities and differences in clinical and molecular findings in 12 Turkish patients
Five new genetic variants in rare bone dysplasias were identified, and tiptoe walking emerged as an early diagnostic clue for one subtype.
Twelve patients with genetically confirmed acromelic dysplasias (including geleophysic dysplasia, WMS1, WMS4, acromicric dysplasia, AHO) were characterized clinically and molecularly, revealing 5 novel variants in extracellular matrix genes and identifying tiptoe walking as an early diagnostic clue for geleophysic dysplasia. The 8-year longitudinal follow-up data expand the genotype-phenotype spectrum of these rare connective tissue disorders.

Why it surfaced
Rare disease, 5 novel variants, longitudinal data. Limited by n=12 but consistent with rare disease evidence tier. Useful for diagnostics and natural history.
