Genes affected

GET1 (HGNC:12790): (guided entry of tail-anchored proteins factor 1) This gene is located in the candidate region for congenital heart disease (CHD) in Down syndrome (DS). It encodes a basic protein that functions as a receptor that promotes insertion of tail-anchored proteins in the endoplasmic reticulum membrane. This gene is located at a maternally-methylated differentially methylated region (DMR); however, its transcription may be biallelic, not imprinted. Alternative splicing results in different transcript variants. A pseudogene has been defined on chromosome 4. [provided by RefSeq, Apr 2017]

Ambry Genetics

Apr 06, 2024

The c.46A>G (p.S16G) alteration is located in exon 1 (coding exon 1) of the WRB gene. This alteration results from a A to G substitution at nucleotide position 46, causing the serine (S) at amino acid position 16 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
