Zornitza Stark gene: HMGCS1 was added gene: HMGCS1 was added to Muscular dystrophy and myopathy_Paediatric. Sources: Literature Mode of inheritance for gene: HMGCS1 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: HMGCS1 were set to 39531736 Phenotypes for gene: HMGCS1 were set to Rigid spine syndrome, MONDO:0019951, HMGCS1-related Review for gene: HMGCS1 was set to GREEN Added comment: Five individuals from four families reported. All individuals presented with spinal rigidity primarily affecting the cervical and dorsolumbar regions, scoliosis, and respiratory insufficiency. Creatine kinase levels were variably elevated. The clinical course worsened with intercurrent disease or certain drugs in some; one individual died from respiratory failure following infection. Muscle biopsies revealed irregularities in oxidative enzyme staining with occasional internal nuclei and rimmed vacuoles. HMGCS1 encodes a critical enzyme of the mevalonate pathway. Notably, biallelic hypomorphic variants in downstream enzymes including HMGCR and GGPS1 are associated with muscular dystrophy. Hmgcs1 mutant zebrafish displayed severe early defects, including immobility at 2 days and death by day 3 post-fertilisation and were rescued by HMGCS1 mRNA. Four variants tested (S447P, Q29L M70T, and C268S) have reduced function compared to wildtype HMGCS1 in zebrafish rescue assays Sources: Literature |
