What are the genetic causes and classifications of brachydactyly?

Brachydactyly encompasses various types with distinct genetic causes and inheritance patterns, primarily following an autosomal dominant inheritance.

Brachydactyly can occur as an isolated malformation or as part of a complex malformation syndrome.
Many different forms of brachydactyly have been identified, with types A3 and D being more common.
The inheritance of isolated brachydactyly is mostly autosomal dominant with variable expressivity.
Prenatal diagnosis may be appropriate in syndromic forms of brachydactyly.

Brachydactyly means having short fingers or toes, and it can be caused by different genes. Some types are more common than others.

The study involved clinical, anthropometric, and radiological evaluations, along with molecular genetic analysis.

The study primarily focuses on isolated forms of brachydactyly and may not cover all syndromic associations.
