brachydactyly-mesomelia-intellectual disability-heart defects syndrome or if brachydactyly is not isolated and is a part of a larger genetic condition.

No visible clubbing – Fluctuation (increased ballotability) and softening of the nail bed only. No visible changes of nails. Mild clubbing – Loss of the normal <165° angle (Lovibond angle) between the nailbed and the fold (cuticula). Schamroth's window (see image) is obliterated. Clubbing is not obvious at a glance. Moderate clubbing ...
