Green List (high evidence)

Additional support for inclusion of gene on panel comes from Yates et al., 2017 (PMID:28425981, Whole-exome sequencing on deceased fetuses with ultrasound anomalies: expanding our knowledge of genetic disease during fetal development). Yates et al., identified a heterozygous de novo variant in RIT1 in a case where the main ultrasound finding was Hydrops, CNS malformation, congenital heart defect (Table 1).

Additional evidence from PMID:30712878: De novo variant identified in RIT1 from fetal exome sequencing in Petrovski et al., 2019 (Whole-exome sequencing in the evaluation of fetal stuctural anomalies: a prospective cohort study, PMID:30712878).

Additional evidence from PMID:30266093: AD/de novo het variant identified in RIT1 from fetal exome sequencing in Normand et al., 2018 (Clinical exome sequencing for fetuses with ultrasound abnormalities and a suspected Mendelian disorder, PMID:30266093).

Additional evidence from PAGE study: Diagnostic Heterozygous variants identified in RIT1 from fetalexome sequencing inLord et al., 2019 (PMID:30712880).

This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Confirmed that phenotype is fetally-relevant: keep on the Fetal anomalies panel as a Green gene.
