Genes affected

DGCR6L (HGNC:18551): (DiGeorge syndrome critical region gene 6 like) This gene, the result of a duplication at this locus, is one of two functional genes encoding nearly identical proteins that have similar expression patterns. The product of this gene is a protein that shares homology with the Drosophila gonadal protein, expressed in gonadal tissues and germ cells, and with the human laminin gamma-1 chain that functions in cell attachment and migration. This gene is located in a region of chromosome 22 implicated in the DiGeorge syndrome, one facet of a broader collection of anomalies referred to as the CATCH 22 syndrome.

The c.544C>T (p.L182F) alteration is located in exon 5 (coding exon 5) of the DGCR6L gene. This alteration results from a C to T substitution at nucleotide position 544, causing the leucine (L) at amino acid position 182 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
