Genes affected
MICOS13 (HGNC:33702): (mitochondrial contact site and cristae organizing system subunit 13) Involved in cristae formation. Located in mitochondrial crista junction and nucleoplasm. Part of MICOS complex. Implicated in combined oxidative phosphorylation deficiency 37. [provided by Alliance of Genome Resources, Apr 2022]
RPL36 (HGNC:13631): (ribosomal protein L36) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 60S subunit. The protein belongs to the L36E family of ribosomal proteins. It is located in the cytoplasm. Transcript variants derived from alternative splicing exist; they encode the same protein. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Jul 2008]

This sequence change creates a premature translational stop signal (p.Tyr26*) in the C19orf70 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in C19orf70 are known to be pathogenic (PMID: 27485409, 27623147). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with C19orf70-related conditions. For these reasons, this variant has been classified as Pathogenic. -
