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. [provided by RefSeq, Jul 2008]

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

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.06921509).

The c.575C>T (p.T192I) alteration is located in exon 6 (coding exon 6) of the ADAMDEC1 gene. This alteration results from a C to T substitution at nucleotide position 575, causing the threonine (T) at amino acid position 192 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
