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 Gene-Disease associations (from GenCC):

• cerebellar atrophy, visual impairment, and psychomotor retardation;

  Inheritance: AR, AD Classification: STRONG, MODERATE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), G2P, Ambry Genetics
• complex neurodevelopmental disorder with motor features

  Inheritance: AD, AR Classification: MODERATE Submitted by: ClinGen
• global developmental delay-visual anomalies-progressive cerebellar atrophy-truncal hypotonia syndrome

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.38).
