Genes affected
EMC1 (HGNC:28957): (ER membrane protein complex subunit 1) This gene encodes a single-pass type I transmembrane protein, which is a subunit of the endoplasmic reticulum membrane protein complex (EMC). Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2012]
EMC1-AS1 (HGNC:54050): (EMC1 antisense RNA 1)

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 29, 2021This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 219099). This premature translational stop signal has been observed in individual(s) with EMC1-related conditions (PMID: 26942288). This sequence change creates a premature translational stop signal (p.Pro874Argfs*21) in the EMC1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EMC1 are known to be pathogenic (PMID: 26572623, 26942288, 29271071). -
