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

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=0.090910286).

Ambry Genetics

Nov 30, 2022

The c.34G>A (p.A12T) alteration is located in exon 1 (coding exon 1) of the ADAMDEC1 gene. This alteration results from a G to A substitution at nucleotide position 34, causing the alanine (A) at amino acid position 12 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
