Genes affected

GET4 (HGNC:21690): (guided entry of tail-anchored proteins factor 4) Enables chaperone binding activity. Involved in cytoplasmic sequestering of protein; maintenance of unfolded protein involved in ERAD pathway; and tail-anchored membrane protein insertion into ER membrane. Located in chromosome; cytosol; and nuclear lumen. Part of BAT3 complex. [provided by Alliance of Genome Resources, Apr 2022]

GET4 links:

SUN1 (HGNC:18587): (Sad1 and UNC84 domain containing 1) This gene is a member of the unc-84 homolog family and encodes a nuclear envelope protein with an Unc84 (SUN) domain. The protein is involved in nuclear anchorage and migration. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2019]

Collection Method: clinical testing

The c.227A>G (p.H76R) alteration is located in exon 2 (coding exon 2) of the GET4 gene. This alteration results from a A to G substitution at nucleotide position 227, causing the histidine (H) at amino acid position 76 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
