Two novel compound heterozygous HOXB1 variants in congenital facial palsy: A case report and a brief review of the literature.

Hereditary congenital facial palsy (HCFP) is a medical condition caused by dysfunction of the seventh cranial nerve. HCFP is characterized by feeding difficulties and dysmorphic features in the orofacial region. In some cases hearing loss, strabismus, limb malformations, and musculoskeletal defects may be associated.

A novel STING variant triggers endothelial toxicity and SAVI disease.

Gain-of-function mutations in STING cause STING-associated vasculopathy with onset in infancy (SAVI) characterized by early-onset systemic inflammation, skin vasculopathy, and interstitial lung disease. Here, we report and characterize a novel STING variant (F269S) identified in a SAVI patient. Single-cell transcriptomics of patient bone marrow revealed spontaneous activation of interferon (IFN) and inflammatory pathways across cell types and a striking prevalence of circulating naïve T cells was observed.
