Acrocallosal syndrome: new findings.

Area of Science:

• Medical Genetics
• Developmental Biology
• Pediatric Neurology

Background:

• Acrocallosal syndrome is a rare genetic disorder characterized by craniofacial anomalies and agenesis of the corpus callosum.
• It is associated with significant developmental delays and physical malformations.
• Understanding the full spectrum of this syndrome is crucial for diagnosis and management.

Observation:

• A 21-month-old female patient presented with classic acrocallosal syndrome features including craniofacial anomalies, agenesis of the corpus callosum, hallux duplication, severe hypotonia, and psychomotor retardation.
• The patient exhibited additional complex anomalies: Dandy-Walker malformation, imperforate anus with rectovaginal fistula, and hypothalamic dysfunction.
• Further complications included hypothyroidism, diabetes insipidus, dysplastic pulmonic valve leaflets, central and obstructive apnea, and pulmonary hypertension.

Findings:

• The presented case expands the known phenotypic spectrum of acrocallosal syndrome.
• The combination of typical and previously unreported features provides valuable data for genetic counseling and research.
• This detailed observation contributes to a more comprehensive understanding of acrocallosal syndrome's variability.

Implications:

• These findings aid in refining diagnostic criteria and genetic counseling for acrocallosal syndrome.
• Further research into the genetic underpinnings and molecular mechanisms of these combined anomalies is warranted.
• Improved delineation of the syndrome facilitates better clinical management and prognostic assessment for affected individuals.
