Red List (low evidence)

Initial gene list and info collated by Carl Fratter (Oxford University Hospitals NHS Trust) January 2019 on behalf of the GMS Mitochondrial specialist test group.
Created: 4 Feb 2019, 1:36 p.m.

Mode of inheritance
BOTH monoallelic and biallelic, autosomal or pseudoautosomal

Anemia, sideroblastic, 4, 182170; Even-plus syndrome, 616854; Also Parkinson disease association?

Ellen McDonagh (Genomics England Curator)

Comment on list classification: Discussed in the Analysis & Interpretation meeting and decided to make this red for now.
Created: 25 Apr 2016, 12:18 p.m.
Comment on list classification: PMID: 26598328 describes the identification of biallelic variants in HSPA9 in three patients (two of which are siblings), with EVEN-PLUS syndrome (a proposed syndrome name), and discussed the evidence for likely effect on HSPA9 function due to its role as a mitochondrial chaperone.
Created: 15 Feb 2016, 11:46 a.m.
Comment on mode of inheritance: One patient was compound heterozygous, the two siblings were homozygous for a seperate mutation. Unaffected parents were heterozygous.
