History Filter Activity
Set Phenotypes
Arina Puzriakova (Genomics England Curator)Phenotypes for gene: ORC1 were changed from Bilateral Microtia; 224690; Meier Gorlin EPS; causes microtia and syndromic features; Meier-Gorlin syndrome 1 to Meier-Gorlin syndrome 1, OMIM:224690; Bilateral Microtia
panel promoted to version 1
Ellen McDonagh (Genomics England Curator)26th Oct 2016: the panels Bilateral microtia version 1.10, Ear malformations with hearing impairment version 0.105, and familial hemifacial microsomia version 0.149 gene panels were combined to create this panel. The panel was revised due to expert review, further curation of evidence and internal clinical evaluation. Ready for promotion to version 1.
