Genes affected

ADAMDEC1 (HGNC:16299): (ADAM like decysin 1) This encoded protein is thought to be a secreted protein belonging to the disintegrin metalloproteinase family. Its expression is upregulated during dendritic cells maturation. This protein may play an important role in dendritic cell function and their interactions with germinal center T cells.

ADAM7-AS1 (HGNC:56152): (ADAM7, ADAMDEC1 and ADAM28 antisense RNA 1)

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
