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.

Had R21 - prenatal findings Persistent clenched hands during repeat scans sinve 20weeks. Nuchal 8mm at 24w, 13mm at 26w. Normal nuchal at 12 wk. Normal range of movement other joints. Fetal echo NAD. Postnatally: Motor delay, hypometric saccades, horizontal nystagmus, dystonia, generalized hypotonia, delayed gross motor development, delayed fine motor development, and congenital finger flexion contractures. PMID:27476654 Table 5 - 1 patient contractures. Emailed Lara Menzies - expert in this gene to see whether phenotype likely linked. Keep amber
