Panel Version: 4.192
This gene and phenotype were reviewed during meetings between November 2023 & July 2024. The meetings included representatives of the North Thames and Central & South R21 testing GLHs and from the R21 Clinical Oversight Group. Clinical review and curation was performed by Natalie Chandler, Alison Male and Lyn Chitty (North Thames GLH), Stephanie Allen, Natalie Bibb, Esther Kinning and Denise Williams (Central & South GLH) and Natalie Canham, Anna De Burca and Samantha Doyle R21 Clinical Oversight Group. Outcome of review: Confirmed that the phenotype is fetally relevant, support adding to the Fetal anomalies panel as a Green gene.

Natalie Chandler (North Thames GLH)

Green List (high evidence)

Green on 5 panels including severe microcephaly - went green in Feb 2023. Six individuals from three families with different homozygous LoF NSRP1 variants identified by Calame et al. 2021 (PMID: 34385670). Main clinical features include ID/DD (6/6), epilepsy (6/6, drug-resistant in 3/6), hypotonia (6/6), appendicular spasticity (6/6), microcephaly (5/6, Z-scores _0.95 to _5.60). Brain abnormalities included under-opercularization (3/4), simplified gyral pattern (3/4), superior and/or inferior cerebellar vermian hypoplasia (3/4), corpus callosum dysgenesis (1/4), and thin brainstem (1/4).
