Mendeliome v1.1170 DBR1 Zornitza Stark Phenotypes for gene: DBR1 were changed from {Encephalitis, acute, infection (viral)-induced, susceptibility to, 11}, MIM# 619441; Viral infections of the brainstem; Ichthyosis (MONDO#0019269), DBR1-related to {Encephalitis, acute, infection (viral)-induced, susceptibility to, 11}, MIM# 619441; Viral infections of the brainstem; Xerosis and growth failure with immune and pulmonary dysfunction syndrome, MIM# 620510
Mendeliome v1.1159 DBR1 Zornitza Stark Phenotypes for gene: DBR1 were changed from {Encephalitis, acute, infection (viral)-induced, susceptibility to, 11}, MIM# 619441; Viral infections of the brainstem to {Encephalitis, acute, infection (viral)-induced, susceptibility to, 11}, MIM# 619441; Viral infections of the brainstem; Ichthyosis (MONDO#0019269), DBR1-related
Mendeliome v1.1158 DBR1 Zornitza Stark edited their review of gene: DBR1: Added comment: PMID: 37656279:
- A homozygous missense as a founder recessive DBR1 variant in four consanguineous families.
- Total of 7 affected children. WES done for one proband from each family.
- Consistent features include prematurity, severe intrauterine growth deficiency, congenital ichthyosis-like presentation (collodion membrane, severe skin peeling and xerosis), and death before the first year of life.
- RNA and protein studies using fibroblasts derived from a patient are supportive of pathogenicity: RNA-seq, rt-qPCR and western blotting, showing marked reduction of DBR1 level and intronic RNA lariat accumulation in the patient sample.
- Haplotype analysis revealed that the four families all share a haplotype extending at least 2.27 Mb around the c.200A>G p.(Tyr67Cys) DBR1 founder variant.
- Authors proposed this is a novel DBR1-related developmental disorder that is distinct from DBR1-related encephalitis susceptibility, and highlighted the apparent lack of correlation with the degree of DBR1 deficiency.; Changed publications: 29474921, 37656279; Changed phenotypes: {Encephalitis, acute, infection (viral)-induced, susceptibility to, 11}, MIM# 619441, Viral infections of the brainstem, Ichthyosis (MONDO#0019269), DBR1-related
