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]

The c.391G>A (p.V131M) alteration is located in exon 4 (coding exon 4) of the WRB gene. This alteration results from a G to A substitution at nucleotide position 391, causing the valine (V) at amino acid position 131 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
