Genes affected

GATD3 (HGNC:1273): (glutamine amidotransferase class 1 domain containing 3) This gene encodes a potential mitochondrial protein that is a member of the DJ-1/PfpI gene family. This protein is overexpressed in fetal Down syndrome brain. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

LOC102725065 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.
