Genes affected

VPS26C (HGNC:3044): (VPS26 endosomal protein sorting factor C) The region of chromosome 21 between genes CBR and ERG (CBR-ERG region), which spans 2.5 Mb on 21q22.2, has been defined by analysis of patients with partial trisomy 21. It contributes significantly to the pathogenesis of many characteristics of Down syndrome, including morphological features, hypotonia, and cognitive disability. The DSCR3 (Down syndrome critical region gene 3) gene is found in this region and is predictated to contain eight exons. DSCR3 is expressed in most tissues examined. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.569C>T (p.T190M) alteration is located in exon 6 (coding exon 6) of the DSCR3 gene. This alteration results from a C to T substitution at nucleotide position 569, causing the threonine (T) at amino acid position 190 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
