Green List (high evidence)

Comment on list classification: Various degrees of cognitive impairment reported (PMID:33230297). However, DD is an early feature often preceding other neurological concerns, and there are enough cases with sufficiently severe ID for inclusion on this panel.

Rating Amber but should be promoted to Green at the next GMS panel update (added 'for-review' tag)

- PMID: 33230297 (2020) - 16 individuals from 11 families with biallelic variants in the RNU7-1 gene. Clinical features were typical of Aicardi–Goutières syndrome, including spasticity, dystonia, epilepsy, peripheral neuropathy, brain calcification, mild skin involvement and delayed psychomotor development. Upregulated interferon signalling was detected in patient blood and fibroblasts. 4/12 variants were observed in 2 or more families - several from different ethnic backgrounds. 8 variants are recorded in gnomAD but at a frequency of ≤0.005, and no biallelic variants were identified in control populations. Some functional data showing a disturbance of histone RNA processing in patient-derived compared to control fibroblasts.
