Overview
Gomez-Lopez-Hernandez syndrome (GLHS) is a rare genetic disorder characterized by rhombencephalosynapsis (RS), parietal alopecia, and trigeminal anesthesia, often accompanied by skull abnormalities, craniofacial dysmorphisms, short stature, and intellectual impairment 1.Diagnosis
Key Diagnostic Criteria: Rhombencephalosynapsis (RS), parietal alopecia, trigeminal anesthesia 1.
Additional Findings: Skull abnormalities, craniofacial dysmorphisms, short stature, intermittent head stereotypies 1.
Neuroimaging: MRI or CT scans may reveal RS but cannot distinguish isolated RS from GLHS 1.
Clinical Signs: Bilateral alopecia present in neonatal period is highly suggestive 1.
Differential Diagnosis: Hernandez syndrome should be distinguished based on clinical features like psychomotor retardation, bulbous nose, and epilepsy 2.Management
No Specific Treatments Mentioned: Management focuses on supportive care addressing individual symptoms and complications 12.
Supportive Care: Tailored interventions for intellectual impairment, epilepsy, and physical abnormalities as needed 12.Special Populations
Pediatrics: Neonatal dysmorphic signs are crucial for early diagnosis; one case reported neonatal death due to esophageal atresia 1.
Comorbidities: Esophageal atresia noted in one neonatal case 1.Key Recommendations
Suspect GLHS in neonates with bilateral alopecia and craniofacial dysmorphisms, and seek neuroimaging for RS (Evidence: Weak 1).
Comprehensive clinical evaluation is essential for distinguishing GLHS from other syndromes with overlapping features (Evidence: Weak 12).
Supportive care should be individualized based on specific clinical manifestations and comorbidities (Evidence: Expert opinion).References
