Cutis verticis gyrata-retinitis pigmentosa-sensorineural deafness syndrome

Cutis verticis gyrata-retinitis pigmentosa-sensorineural deafness syndrome is an extremely rare genetic disorder characterized by the combination of three cardinal features: cutis verticis gyrata (thickened, folded skin on the scalp resembling the convolutions of the brain surface), retinitis pigmentosa (a progressive degenerative disease of the retina leading to vision loss), and sensorineural hearing loss. This condition affects multiple body systems including the skin, eyes, and auditory system. The cutis verticis gyrata component manifests as deep furrows and ridges on the scalp, which may become apparent during childhood or adolescence. Retinitis pigmentosa causes progressive deterioration of the photoreceptor cells in the retina, typically beginning with night blindness and loss of peripheral vision, potentially progressing to significant visual impairment. The sensorineural deafness involves damage to the inner ear or auditory nerve pathways, resulting in hearing difficulties of variable severity. This syndrome has been reported in very few families in the medical literature. The exact underlying genetic mechanism remains incompletely characterized. There is currently no curative treatment available. Management is supportive and multidisciplinary, involving dermatological care for the scalp condition, ophthalmological monitoring and low-vision aids for retinitis pigmentosa, and audiological support including hearing aids or cochlear implants for sensorineural deafness. Genetic counseling is recommended for affected families.
