| Severe microcephaly v8.41 | NRDC | Ida Ertmanska Added comment: Comment on list classification: There are 13 individuals reported with biallelic NRDC variants and microcephaly. While severity is not stated, this is a consistent feature in all patients. Hence, NRDC should be promoted to Green for Severe microcephaly, with MOI set to BIALLELIC, autosomal or pseudoautosomal. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Ida Ertmanska gene: NRDC was added gene: NRDC was added to Severe microcephaly. Sources: Literature Q1_26_promote_green tags were added to gene: NRDC. Mode of inheritance for gene: NRDC was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: NRDC were set to 41734767 Phenotypes for gene: NRDC were set to microcephaly, MONDO:0001149; neurodevelopmental disorder, MONDO:0700092; Optic neuropathy, HP:0001138 Review for gene: NRDC was set to GREEN Added comment: PMID: 41734767 Pehlivan et al., 2026 Report of 14 individuals from nine unrelated families carrying homozygous NRDC pathogenic variants (some reported previously). Common clinical features include severe to profound developmental delay/intellectual disability (12/12), microcephaly (13/13), prematurity (5/13), lethality in the first 3 years of life (9/14), seizures (7/11), joint contractures (4/8), eye/visual abnormalities (5/7 - 3 with optic atrophy, 1 with nystagmus, and 1 case of visual inattentiveness), and abnormal brain imaging studies ranging from diffuse atrophy to lissencephaly (8/11). The identified variants include two splice, three frameshift, and three missense variants. NRDC is not yet associated with a phenotype in OMIM (accessed 9th Mar 2026). Sources: Literature |
