Rebecca Foulger (Genomics England curator)

Green List (high evidence)

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.

Communication from Deirdre Cilliers, Oxford University Hospitals (via email, February 2019) to support Green rating: Yes [TPM2 should be on the Fetal anomalies panel]. Distal arthrogryposis is seen relatively frequently on ultrasound scan. Often a diagnosis is of help as it gives information about the chance (or not) of learning difficulties when there is a diagnosis of arthrogryposis in the feta’s. The phenotype is also relatively straightforward to identify on ultrasound scan and this would make variant interpretation better.

Comment on list classification: Updated rating from Amber to Green: Rated Green on relevant V1 panel(s) PLUS phenotype (ARTHROGRYPOSIS, DISTAL, TYPE 1 ) appropriate for fetal panel, as noted by Helen Brittain and Anna de Burca (Genomics England Clinical team). 2 unrelated cases listed in OMIM for ARTHROGRYPOSIS disorders- TPM2 is Green on the Arthrogryposis panel based on these cases plus two Green reviews. Therefore reasonable to promote to Green on this fetal panel based on ARTHROGRYPOSIS phenotype.
