Mendeliome v0.13786 DROSHA Zornitza Stark Marked gene: DROSHA as ready
Mendeliome v0.13786 DROSHA Zornitza Stark Gene: drosha has been classified as Amber List (Moderate Evidence).
Mendeliome v0.13786 DROSHA Zornitza Stark Classified gene: DROSHA as Amber List (moderate evidence)
Mendeliome v0.13786 DROSHA Zornitza Stark Gene: drosha has been classified as Amber List (Moderate Evidence).
Mendeliome v0.13784 DROSHA Lucy Spencer gene: DROSHA was added
gene: DROSHA was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: DROSHA was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: DROSHA were set to 35405010
Phenotypes for gene: DROSHA were set to Neurodevelopmental disorder (MONDO#0700092), DROSHA-related
Review for gene: DROSHA was set to AMBER
Added comment: 2 individuals with profound intellectual disability, epilepsy, white matter atrophy, microcephaly, and dysmorphic features, who carry damaging de novo heterozygous variants in DROSHA. Both variants are missense, absent from gnomad. Both individuals noted to have Rett-like features.

Functional studies in patient fibroblasts showed one of the missense altered the expression of mature miRNA. Fruit fly models with homozygous LOF variants die during larval stages. introduction of the missense seen in the patients was able to partially rescue this phenotype suggesting LOF is not the mechanism.
