Mendeliome v1.4200 NRDC Rylee Peters gene: NRDC was added
gene: NRDC was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: NRDC was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: NRDC were set to 41449824; 28017472; 34582790; 19935654
Phenotypes for gene: NRDC were set to Neurodevelopmental disorder, MONDO:0700092, NRDC-related
Review for gene: NRDC was set to AMBER
Added comment: Two unrelated families reported with the same homozygous NMD-predicted frameshift variant. PMID: 41449824 describes two affected siblings with severe neurodevelopmental disorder (developmental delay, microcephaly, hypotonia, seizures, absent speech). PMID: 28017472 reports one individual with severe global developmental delay, ataxia, progressive neurodegeneration, and acquired microcephaly.

PMID: 34582790 describes an additional homozygous splice variant (NRDC c.3081-2A>G) in an infant with developmental delay, ventricular dilatation and large nevi; however, the individual was also homozygous for a pathogenic NANS missense variant (c.635T>C; p.I212T), which has an established gene–disease association.

PMID: 19935654 | Nrd1−/− mice show reduced brain size, thin cerebral cortex, central and peripheral hypomyelination, with motor impairment and cognitive deficits.
