A novel mutation in MYORG leads to primary familial brain calcification and cerebral infarction

Liang Gao et al.

Summary: This study reported a young patient with primary familial brain calcification (PFBC) carrying a novel homozygous mutation in the MYORG gene and presenting with cerebral infarction involving the posterior limb of the right internal capsule.

Primary familial brain calcification in a patient with a novel compound heterozygous mutation in MYORG presenting with an acute ischemic stroke: a case report

Qijie Yang et al.

Summary: Primary familial brain calcification (PFBC) is a genetically heterogeneous disease characterized by extensive intracranial calcium deposition, with pathogenic variants in six genes associated with the condition. PFBC patients may present with various symptoms, including movement disorders, cognitive impairment, and psychiatric symptoms, with acute cerebrovascular attacks being rare. This case report highlights a PFBC patient with a novel compound heterozygous mutation in MYORG who experienced an acute ischemic stroke, emphasizing the need for further exploration of the association between acute ischemic strokes and PFBC.

Basal ganglia calcification in hypoparathyroidism and pseudohypoparathyroidism: local and systemic metabolic mechanisms

G. Zavatta et al.

Summary: Hypoparathyroidism and pseudohypoparathyroidism are rare disorders of mineral metabolism associated with soft tissue calcification. Maintaining normal calcium/phosphorus ratio and serum phosphate levels may help mitigate the progression of basal ganglia calcification. Further research is needed to explore the pathophysiology and treatment options for these disorders.

Case Report First pediatric case with primary familial brain calcification due to a novel variant on the MYORG gene and review of the literature

Leman Tekin Orgun et al.

Summary: Variants in the MYORG gene are associated with AR-PFBC, with 74 cases evaluated so far. Patients present with a wide range of ages and commonly exhibit speech impairment, movement disorder, and cerebellar signs, along with basal ganglia calcification.

Mutation Analysis of MYORG in a Chinese Cohort With Primary Familial Brain Calcification

Yi-Heng Zeng et al.

Summary: The study revealed a link between MYORG gene mutations and PFBC in Chinese patients, with affected individuals showing a consistent clinical spectrum including brain calcification and parkinsonism. Novel MYORG variants were identified, expanding the understanding of genetic and phenotypic diversity in PFBC-MYORG.

Severe brain calcification and migraine headache caused by SLC20A2 and PDGFRB heterozygous mutations in a five-year-old Chinese girl

Hao Sun et al.

Summary: This study identified a PFBC case with both SLC20A2 and PDGFRB heterozygous mutations. The parents of the case carried a single heterozygous mutation in either SLC20A2 or PDGFRB, showing varying degrees of brain calcification.

Genotype-Phenotype Relations in Primary Familial Brain Calcification: Systematic MDSGene Review

Alexander Balck et al.

Summary: This systematic review summarizes data on individuals with confirmed genetic forms of primary familial brain calcification, revealing that some carriers of certain gene mutations are clinically unaffected, and different gene variants show varying penetrance. Clinically affected patients often exhibit motor or non-motor symptoms, with parkinsonism and speech disturbance being the most common motor manifestations, and cognitive deficits, headache, and depression being major non-motor symptoms.

Idiopathic basal ganglia calcification associated with new MYORG mutation site: A case report

Bei-Ni Fei et al.

Summary: Idiopathic basal ganglia calcification (IBGC) is a neurodegenerative disease characterized by symmetrical calcification of basal ganglia and other brain regions. Detection of MYORG mutation is crucial for better understanding and potential treatments, especially in patients without an obvious family history.
