Overview of Preaxial Polydactyly Colobomata Mental Retardation
Polydactyly, also known as hyperdactyly or hexadactyly, is characterized by extra fingers or toes․ It can be part of syndromic polydactyly or occur independently․ Preaxial polydactyly colobomata mental retardation involves additional complexities like mental retardation, colobomata, and more․
Definition and Classification of Polydactyly
Polydactyly, also known as hyperdactyly or hexadactyly, is the most common hereditary limb anomaly characterized by extra fingers or toes․ It can present as syndromic or non-syndromic polydactyly, which includes various classification types such as preaxial, central, and postaxial polydactyly based on the location of the additional digits․
Clinical Manifestations
Disease presentation often includes extra fingers or toes, mental retardation, and other associated features like colobomata․
Syndromic Presentation
Syndromic presentation of the disease often includes a combination of extra fingers or toes, mental retardation, and colobomata, demonstrating a complex clinical profile․
Neurological and Ocular Characteristics
The disease exhibits a range of neurological manifestations including mental retardation, and may present with ocular abnormalities such as colobomata, illustrating a diverse clinical spectrum․
Genetic Factors and Inheritance Patterns
Genetic factors play a crucial role in conditions like preaxial polydactyly colobomata mental retardation, often demonstrating autosomal recessive syndromes or X-linked transmission patterns․
Autosomal Recessive Syndromes
The condition of preaxial polydactyly colobomata mental retardation often shows autosomal recessive inheritance patterns, with various associated syndromes suggesting a genetic link․
X-Linked Transmission
This condition, such as Biemond syndrome type 2, illustrates X-linked transmission involving elements like mental retardation, coloboma, polydactyly, and hypogonadism, emphasizing the genetic complexity of the disorder․
Specific Syndromes Related to Preaxial Polydactyly Colobomata Mental Retardation
Pfeiffer Mayer Syndrome, also known as Preaxial Polydactyly-Colobomata-Intellectual Disability Syndrome, features growth retardation, intellectual deficit, preaxial polydactyly, and colobomatous anomalies in affected individuals․
Pfeiffer Mayer Syndrome
Pfeiffer Mayer Syndrome, known as Preaxial Polydactyly-Colobomata-Intellectual Disability Syndrome, is characterized by growth retardation, intellectual deficit, preaxial polydactyly, and colobomatous anomalies․
Bardet-Biedl Syndrome Type 2
Bardet-Biedl Syndrome Type 2, a genetic disorder closely related to Biemond syndrome, exhibits a range of characteristics including obesity, moderate mental retardation, dysmorphic extremities with polydactyly, and retinitis pigmentosa․ It is an inherited syndrome typically involving symptoms like coloboma and preaxial polydactyly․
