Genes affected

EMC4 (HGNC:28032): (ER membrane protein complex subunit 4) Contributes to membrane insertase activity. Involved in protein insertion into ER membrane by stop-transfer membrane-anchor sequence and tail-anchored membrane protein insertion into ER membrane. Is integral component of endoplasmic reticulum membrane. Part of EMC complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Mar 22, 2023

The c.8C>T (p.A3V) alteration is located in exon 1 (coding exon 1) of the EMC4 gene. This alteration results from a C to T substitution at nucleotide position 8, causing the alanine (A) at amino acid position 3 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
