Eleanor Williams (Genomics England Curator)

Comment on list classification: Following review from Zornitza Stark changing the rating of THOC1 from grey to amber as there is one large family plus functional data to support the proposal that a variant in THOC1 is associated with hearing loss.

I don't know

Missense variant identified and segregated with adult-onset hearing loss in 9 affected family members. 12 unaffected individuals also tested.
Functional studies showed THOC1 was expressed in mouse and zebrafish hair cells. Furthermore, thoc1 deficiency caused the reduction of hair cell numbers in zebrafish and the hypomorphic thoc1 in mouse induced hair cell apoptosis.
