Phenotypic analysis characterizes distinctive skeletal malformations across inherited brachydactyly subtypes, highlighting hands as key diagnostic markers in children with short stature.

Key Points

To delineate distinct malformation patterns across inherited brachydactyly subtypes and establish clinical criteria to prevent overlooking underlying skeletal dysplasia in short stature.
Analyzed clinical and anatomical patterns across various inherited brachydactyly subtypes, including types A-1, B, C, and E.
Evaluated associated growth phenotypes such as overall stature and specific bone length proportions in the hands.
Type A-1 exhibits proportionate shortening of middle phalanges, Type B presents an amputation-like defect, Type C features a relatively prolonged fourth middle phalanx, and Type E shows shortened metacarpals and distal phalanges.
Short stature consistently associates with types A-1 and E, and occurs variably in type C.
Mild brachydactyly expressions risk being missed in children presenting with proportionate short stature unless radiographic assessment detects subtle phalangeal or metacarpal anomalies.
