Combined oxidative phosphorylation deficiency 17	AR	Biochemical; Cardiovascular	The condition can include severe cardiac sequelae, such as hypertrophic cardiomyopathy, and though some individuals have been described as not responding to therapy, others have been reported as benefitting from cardiac surveillance and early insitution of cardioprotective therapy and and biochemical dietary and medical treatment (eg, high-fat diet, coenzyme Q10, riboflavin, thiamine, and carnitine)	Biochemical; Cardiovascular; Neurologic	23849775

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ELAC2 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000018127.7. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function: FUNCTION: Zinc phosphodiesterase, which displays mitochondrial tRNA 3'-processing endonuclease activity. Involved in tRNA maturation, by removing a 3'-trailer from precursor tRNA. {ECO:0000269|PubMed:21593607}.;
Disease: DISEASE: Combined oxidative phosphorylation deficiency 17 (COXPD17) [MIM:615440]: An autosomal recessive disorder of mitochondrial dysfunction characterized by onset of severe hypertrophic cardiomyopathy in the first year of life. Other features include hypotonia, poor growth, lactic acidosis, and failure to thrive. The disorder may be fatal in early childhood. {ECO:0000269|PubMed:23849775}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
