basal ganglia calcification, idiopathic, 10, autosomal recessive

Basal ganglia calcification, idiopathic, 10, autosomal recessive is a neurological condition characterized by abnormal calcium deposits in various regions of the brain. The condition is associated with pathogenic variants in the CMPK2 gene, which is thought to play a role in cellular processes that, when disrupted, may lead to these calcifications. Affected individuals typically present with features that are identified on imaging studies, although precise prevalence information is not well established. The condition is inherited in an autosomal recessive pattern, meaning that two copies of the altered gene are required for the condition to manifest.

The clinical presentation is largely defined by brain calcifications, with imaging often revealing calcification in the globus pallidus, thalamus, and cerebellum, which are consistently observed. Additional features, seen in a portion of affected individuals, include intracerebral periventricular calcifications, cognitive impairment, ataxia, dysarthria, and antinuclear antibody positivity. Some patients may also present with signs of inflammation in the cerebrospinal fluid, as indicated by CSF pleocytosis. Not all individuals experience every feature, and severity varies considerably.

Genetic studies have identified variants in the CMPK2 gene as being associated with basal ganglia calcification, idiopathic, 10, autosomal recessive. CMPK2 is involved in key cellular processes, and disruptions in its function are believed to contribute to the abnormal deposition of calcium in the brain. This condition is inherited in an autosomal recessive pattern, which means that an individual must inherit two copies of the altered gene, one from each parent, to develop the condition. Families with a history of the disorder may benefit from genetic counseling to understand potential recurrence risks.

Currently, management focuses on supportive care and symptom management. As there are no FDA-approved or foundational therapies specifically linked to this condition, treatment is tailored to the needs of the individual and typically involves a multidisciplinary team. Clinicians may advise interventions to address specific symptoms such as ataxia or speech difficulties, and genetic counseling is recommended to help families understand the inheritance pattern and guide family planning. Patients should discuss treatment options with their healthcare team to determine which supportive therapies may be most appropriate.

The long-term outlook for individuals with basal ganglia calcification, idiopathic, 10, autosomal recessive is variable, with outcomes depending on the severity of symptoms and the age at diagnosis. With current standards of care, many individuals are able to manage their symptoms with supportive treatments, and modern care continues to improve quality of life. Outcomes described in medical literature continue to evolve as standards of care improve, and the condition may progress, stabilize, or show a variable course in different individuals. Families are encouraged to seek genetic counseling and connect with specialist teams to explore treatment options and management strategies that are appropriate for their unique situation.

Clinical trials are underway exploring new treatment approaches for this condition. Individuals interested in clinical trials can search ClinicalTrials.gov or consult their care team about eligibility.
