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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.203G>A (p.R68H) alteration is located in exon 3 (coding exon 3) of the EMC4 gene. This alteration results from a G to A substitution at nucleotide position 203, causing the arginine (R) at amino acid position 68 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
