Genes affected
DNAJC19 (HGNC:30528): (DnaJ heat shock protein family (Hsp40) member C19) The protein encoded by this gene is thought to be part of a complex involved in the ATP-dependent transport of transit peptide-containing proteins from the inner cell membrane to the mitochondrial matrix. Defects in this gene are a cause of 3-methylglutaconic aciduria type 5 (MGA5), also known as dilated cardiomyopathy with ataxia (DCMA). Alternative splicing of this gene results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 1, 2, 6, 10, 14 and 19. [provided by RefSeq, Jan 2012]

Submissions by phenotype

3-methylglutaconic aciduria type 5 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 27, 2021This sequence change affects the initiator methionine of the DNAJC19 mRNA. The next in-frame methionine is located at codon 26. This variant is present in population databases (rs372756221, ExAC 0.03%). This variant has not been reported in the literature in individuals affected with DNAJC19-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
