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.203C>T (p.S68L) alteration is located in exon 2 (coding exon 2) of the GET4 gene. This alteration results from a C to T substitution at nucleotide position 203, causing the serine (S) at amino acid position 68 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
