Genes affected

DGCR6 (HGNC:2846): (DiGeorge syndrome critical region gene 6) DiGeorge syndrome, and more widely, the CATCH 22 syndrome, are associated with microdeletions in chromosomal region 22q11.2. The product of this gene shares homology with the Drosophila melanogaster gonadal protein, which participates in gonadal and germ cell development, and with the gamma-1 subunit of human laminin. This gene is a candidate for involvement in DiGeorge syndrome pathology and in schizophrenia. [provided by RefSeq, Nov 2008]

The c.386G>A (p.R129Q) alteration is located in exon 4 (coding exon 4) of the DGCR6 gene. This alteration results from a G to A substitution at nucleotide position 386, causing the arginine (R) at amino acid position 129 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
