Fetal anomalies v2.0 DBR1 Gene migrated from ENSG00000138231 to ENSG00000138231 (gene set migration)
Fetal anomalies v1.143 DBR1 Zornitza Stark Tag founder tag was added to gene: DBR1.
Fetal anomalies v1.143 DBR1 Seb Lunke Marked gene: DBR1 as ready
Fetal anomalies v1.143 DBR1 Seb Lunke Gene: dbr1 has been classified as Amber List (Moderate Evidence).
Fetal anomalies v1.143 DBR1 Seb Lunke Phenotypes for gene: DBR1 were changed from Prematurity, severe intrauterine growth deficiency, congenital ichthyosis-like presentation, and death before the first year of life to Ichthyosis (MONDO#0019269), DBR1-related
Fetal anomalies v1.142 DBR1 Chern Lim Deleted their comment
Fetal anomalies v1.142 DBR1 Chern Lim 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 phenotypes: Ichthyosis (MONDO#0019269), DBR1-related
