Polysyndactyly type Haas is characterized by complete syndactyly of all fingers with polydactyly‚ resulting in a cup-shaped appearance of the hand․
Definition and Characteristics
Polysyndactyly type Haas is a rare congenital anomaly characterized by complete syndactyly of all fingers along with polydactyly‚ resulting in a unique hand appearance․ The condition typically involves six metacarpals and six digits with fusion of phalanges‚ sometimes forming a conglomerate mass of bones․ It can be associated with abnormalities in the ZRS region‚ impacting limb development․ Different variants of syndactyly have been reported‚ with Haas type polysyndactyly presenting as a distinctive form within this spectrum of limb malformations․
Genetic Aspects of Polysyndactyly type Haas
Polysyndactyly type Haas is known for being associated with complete cutaneous fusion of all fingers and polydactyly‚ typically involving six digits and metacarpals․
Inheritance Pattern
Polysyndactyly type Haas exhibits an autosomal dominant pattern of inheritance‚ with complete cutaneous syndactyly of all fingers and polydactyly being the key features․
Syndromes Associated with Syndactyly
Polysyndactyly type Haas may also present as a syndromic form of limb malformation‚ distinct from isolated syndactyly‚ and could be associated with other genetic syndromes like triphalangeal thumb-polysyndactyly syndrome or Laurin-Sandrow syndrome․
Clinical Presentation and Diagnosis
Clinically‚ Polysyndactyly type Haas is characterized by complete syndactyly of all fingers along with polydactyly‚ resulting in a cup-shaped appearance of the hand․ Diagnosis involves physical examination and possibly imaging studies to assess the extent of the anomalies present․
Symptoms and Physical Features
