Introduction
Postaxial polydactyly is a congenital condition characterized by extra digits on the pinky side of hands or feet․ When occurring with mental retardation, it can be associated with various genetic syndromes and health issues․
Postaxial polydactyly combined with mental retardation is a condition involving the presence of extra fingers or toes, typically on the pinky side, along with intellectual disability․ This condition can be linked to various genetic syndromes, impacting an individual’s physical and cognitive development․
Acrocallosal Syndrome
Acrocallosal Syndrome, also known as Schinzel Acrocallosal syndrome, is a rare genetic disorder characterized by postaxial polydactyly and absence of the corpus callosum․ It typically manifests at birth․
Characteristics and Inheritance
Acrocallosal Syndrome is recognized by features such as postaxial polydactyly, absence of the corpus callosum, and unique dysmorphic traits․ Although suggested as autosomal recessive, the inheritance pattern can sometimes appear sporadically, indicating complexity in genetic transmission․

Bardet-Biedl Syndrome-7 (BBS7)
Bardet-Biedl Syndrome-7 (BBS7) is an autosomal recessive disorder characterized by retinitis pigmentosa, postaxial polydactyly, mental retardation, obesity, renal anomalies, and hypogenitalism․
Genetic Disorder Overview
Bardet-Biedl Syndrome-7 (BBS7) is an autosomal recessive disorder characterized by features such as retinitis pigmentosa, postaxial polydactyly, mental retardation, obesity, renal anomalies, and hypogenitalism․ Mutations in the BBS7 gene contribute to this syndrome’s manifestation․
Smith-Lemli-Opitz Syndrome is an autosomal recessive disorder associated with congenital malformations, including postaxial polydactyly and mental retardation․
Smith-Lemli-Opitz Syndrome
Smith-Lemli-Opitz Syndrome is an autosomal recessive disorder causing congenital malformations like postaxial polydactyly and mental retardation, often linked to 7-dehydrocholesterol reductase deficiency․
Goossens-Devriendt Syndrome is characterized by intrauterine growth retardation, congenital heart defect, postaxial polydactyly, brain malformation, abnormal hair, and marked facial dysmorphism․
Characteristics and Impact
Goossens-Devriendt Syndrome is recognized by features such as intrauterine growth retardation, congenital heart defect, postaxial polydactyly, brain malformation, abnormal hair, and marked facial dysmorphism․ These characteristics can significantly impact the individual’s health and development․

Genetic Syndromes and Polydactyly
Various congenital conditions are associated with polydactyly, with postaxial polydactyly and preaxial polydactyly being the most common types, each indicating specific genetic associations and implications․
Various Disorders Linked to Postaxial Polydactyly
Postaxial polydactyly is associated with syndromes like Young-Simpson syndrome, megalencephaly, polymicrogyria, Bardet-Biedl syndrome-7, and Smith-Lemli-Opitz syndrome, each presenting unique traits and complexities impacting individuals’ health․
Health Problems in Individuals with Intellectual Disabilities
In individuals with intellectual disabilities, there may be associated health issues such as seizures, mood disorders, motor skill impairment, vision problems, and hearing difficulties․ These health concerns can impact overall well-being․
Associated Health Issues
Individuals with postaxial polydactyly and mental retardation may encounter seizures, hypothyroidism, heart defects, facial dysmorphism, intellectual disability, growth retardation, transient hypothyroidism, macular degeneration, torticollis, and other health complications impacting their well-being and daily life․
Ciliopathies and Postaxial Polydactyly
The relationship between ciliopathies and postaxial polydactyly is significant, as many genetic syndromes associated with cilia dysfunction, known as ciliopathies, show a strong correlation with postaxial polydactyly․ This link underscores the importance of ciliary function in the development of various syndromes involving postaxial polydactyly and related health complications․
Relationship Between Ciliopathies and Postaxial Polydactyly
The relationship between ciliopathies and postaxial polydactyly is significant, with many genetic syndromes linked to cilia dysfunction showing a strong correlation with postaxial polydactyly․ This association underscores the crucial role of ciliary function in the development of syndromes related to postaxial polydactyly and associated health issues․
Psychomotor Retardation and Mental Health
Psychomotor retardation can slow down mental and physical activities, affecting thinking processes and body movements, impacting mental health and overall well-being․
Effects of Psychomotor Retardation on Mental Health
Psychomotor retardation can impact both mental and physical activities, affecting an individual’s thinking processes, cognitive functions, and overall well-being․ This can lead to challenges in daily life and social interactions, potentially resulting in emotional distress and hindered mental health outcomes․
