AR cardiomyopathy encephalopathy: HGMD only 1 variant: CM112438 Hypertrophic cardiomyopathy, fatal neonatal DM COA5 The A53P substitution does not exhibit a shift in polarity and displays a decrease in Kyte-Doolittle hydrophobicity from 1.8 to -1.6. Approximately 0.88% of missense mutations in HGMD are Ala-Pro. The mutation occurs 22 amino acids from the end of the protein. Huigsloot (2011) Am J Hum Genet 88: 488 PubMed: 21457908.

Ellen McDonagh (Genomics England Curator)

Comment when marking as ready: This gene should remain Amber due to the overall review and evidence assessment from the GMS mitochondrial specialist test group, submitted by Carl Fratter.
Created: 10 May 2019, 11:17 a.m.
Comment on list classification: This gene has been demoted to Amber until further evidence is provided. This gene is currently Red on the Mitochondrial disorders panel (code 112, Version 1.132) - further evidence needs to be submitted to support promoting this gene family member to Green.
Created: 29 Mar 2019, 11:35 a.m.
Comment when marking as ready: Does not seem to be enough evidence at the current time for this gene to be green.
Created: 26 Feb 2016, 4:04 p.m.
Comment on list classification: Only one family report, a possible DD gene, has a question mark by the phenotype in OMIM as only seen in one family.
