Arina Puzriakova (Genomics England Curator)

Comment on list classification: At least 6 families have been reported in literature with heterozygous variants in this gene and lymphedema which support inclusion on this panel with a Green rating at the next GMS panel update.

- PMID: 38820174 - three unrelated cases with different predicted pathogenic variants in the TIE1 gene identified in a primary lymphedema cohort of 755 individuals. Each family had an unaffected carrier indicating reduced penetrance. The TIE1 receptor, in complex with TIE2, plays a role in blood and lymphatic vessel development. The premature stop codon encoded an inactive truncated extracellular protein with decreased mRNA stability, while the missense variants decreased TIE1 signalling. Modelling the two missense variants in mice showed that the variants cause edema and are lethal in homozygous mice.

Miel Theunis (UZ Leuven)

Green List (high evidence)

The expert group of M. Vikkula has shown that variants with a loss-of-function effect (nonsense and missense) are associated with late-onset (puberty or later) lymphedema.

Ivone Leong (Genomics England Curator)

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with a relevant phenotype in OMIM but not in Gene2Phenotype. Based on the expert review this gene has been given an Amber rating until more evidence is available.

I don't know

Three families reported, supportive animal model, though variants are missense and present at a low frequency in gnomad, hence Amber rating suggested.
