Genes affected

DGCR2 (HGNC:2845): (DiGeorge syndrome critical region gene 2) Deletions of the 22q11.2 have been associated with a wide range of developmental defects (notably DiGeorge syndrome, velocardiofacial syndrome, conotruncal anomaly face syndrome and isolated conotruncal cardiac defects) classified under the acronym CATCH 22. The DGCR2 gene encodes a novel putative adhesion receptor protein, which could play a role in neural crest cells migration, a process which has been proposed to be altered in DiGeorge syndrome. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

The c.1628G>A (p.R543H) alteration is located in exon 10 (coding exon 10) of the DGCR2 gene. This alteration results from a G to A substitution at nucleotide position 1628, causing the arginine (R) at amino acid position 543 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
