autosomal recessive nonsyndromic hearing loss 104

Autosomal recessive nonsyndromic hearing loss 104 is a condition characterized predominantly by profound sensorineural hearing impairment that is present from birth. It is caused by mutations in the RIPOR2 gene, which affect the normal function of the auditory system. Affected individuals generally experience prelingual hearing loss, with absent brainstem auditory responses as a defining feature. Although exact prevalence estimates are not specified, the condition is recognized as a genetically inherited cause of hearing loss.

The most characteristic features of this condition include prelingual sensorineural hearing impairment and absent brainstem auditory responses, both of which are consistently observed in all affected individuals. These clinical findings typically lead to early identification of hearing challenges in infancy. Not all individuals may experience additional symptoms beyond hearing impairment, and severity can vary. That not all individuals experience all features, and severity varies considerably.

This condition is caused by mutations in the RIPOR2 gene. The RIPOR2 protein is important for the proper functioning of the auditory system, and mutations can disrupt normal signaling processes required for hearing. It is inherited in an autosomal recessive pattern, which means that an affected individual has inherited one mutated copy of the gene from each parent. As a result, parents of an affected child often do not show any symptoms, but both may be carriers of the mutation, and there is a 25% chance of recurrence with each pregnancy.

Currently, management of autosomal recessive nonsyndromic hearing loss 104 focuses on supportive care and symptom management, as no FDA-approved or foundational therapies are specifically linked to this condition. Treatment is tailored to the individual and typically involves a multidisciplinary team, which may include hearing specialists and audiologists to optimize hearing outcomes. Genetic counseling is an important resource for families to understand inheritance risks and to discuss potential interventions that may support communication and development. Patients should discuss treatment options with their healthcare team to determine which therapies may be appropriate for their specific situation.

The long-term outlook for individuals with autosomal recessive nonsyndromic hearing loss 104 varies, with outcomes depending on factors such as the degree of hearing impairment, early diagnosis, and access to supportive interventions. With current standards of care, many individuals benefit from early intervention services, hearing aids, or other assistive technologies, which can significantly improve communication and quality of life. Outcomes described in medical literature continue to evolve as standards of care improve. Families often find it helpful to connect with specialists experienced in pediatric audiology and genetic counseling to explore available resources and support.
