Pre and post axial polysyndactyly, microcephaly and ptosis

Area of Science:

• Genetics
• Pediatrics
• Clinical Case Study

Background:

• Consanguinity, defined as mating between related individuals, increases the risk of autosomal recessive genetic disorders.
• Genetic factors are crucial in the etiology of congenital anomalies and developmental disorders.
• Understanding rare genetic syndromes aids in diagnosis and management.

Observation:

• A five-year-old boy of Iranian descent presented with a complex spectrum of congenital anomalies.
• The patient's parents were related (first and second cousins), suggesting a potential genetic link.
• Clinical features included short stature, psychomotor retardation, microcephaly, and various craniofacial and limb abnormalities.

Findings:

• The boy exhibited microcephaly, ptosis, dacryostenosis, partial left nerve deafness, high arched palate, bifid uvula, and fused incisors.
• Skeletal anomalies included asymmetric polysyndactyly (preaxial and postaxial), brachyphalangy, kyphosis, and spina bifida occulta.
• This specific constellation of multiple anomalies in a single patient appears to be previously unreported in medical literature.

Implications:

• This case highlights the importance of considering genetic counseling in consanguineous families presenting with multiple congenital anomalies.
• Further research may elucidate the specific genetic mutation(s) responsible for this unique phenotype.
• Detailed documentation of rare cases contributes valuable data for genetic databases and future research into complex genetic disorders.
