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]

GET1 links:

GET1-SH3BGR (HGNC:54635): (GET1-SH3BGR readthrough) This locus represents naturally occurring readthrough transcription between the neighboring WRB (tryptophan rich basic protein) and SH3BGR (SH3 domain binding glutamate-rich protein) genes on chromosome 21. Readthrough transcripts may encode fusion proteins that shares sequence identity with each individual gene product. [provided by RefSeq, Apr 2017]

Collection Method: clinical testing

The c.166A>G (p.M56V) alteration is located in exon 2 (coding exon 2) of the WRB gene. This alteration results from a A to G substitution at nucleotide position 166, causing the methionine (M) at amino acid position 56 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
