Sophie Hambleton (Newcastle University)

Red List (low evidence)

Deficiency of C8g is associated with mutations in C8A in complement factor 8 deficiency type I (C8AG deficiency) but no evidence of mutations within C8G itself associating with any disease phenotype as far as I can see.

Comment on list classification: External expert review notes Red status due to no evident link to immunodeficiency, so demoted to Red on this panel until further evidence from GRID

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.
