Periventricular Grey Matter Heterotopia v0.14 TMTC3 Zornitza Stark Marked gene: TMTC3 as ready
Periventricular Grey Matter Heterotopia v0.14 TMTC3 Zornitza Stark Gene: tmtc3 has been classified as Red List (Low Evidence).
Periventricular Grey Matter Heterotopia v0.14 TMTC3 Zornitza Stark Classified gene: TMTC3 as Red List (low evidence)
Periventricular Grey Matter Heterotopia v0.14 TMTC3 Zornitza Stark Gene: tmtc3 has been classified as Red List (Low Evidence).
Periventricular Grey Matter Heterotopia v0.10 TMTC3 Paul De Fazio changed review comment from: Mostly associated with cobblestone lissencephaly in (6 unrelated families with biallelic variants, PMID: 27773428).

However in 3/4 siblings of another family (PMID: 28973161) biallelic variants were not associated with cobblestone lissencephaly, but periventricular hetertopia instead. The 4th sibling had a normal brain. Animal model studies (Drosophila and rat) support a role for this gene in neurodevelopment.

Although I thought it worth having this gene on this panel I have rated it Red as it is a single family reported with this phenotype, with not all members affected, and it is a different phenotype to that reported previously (i.e. very much 'low evidence').
