Variant 8-24392304-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_014479.3(ADAMDEC1):c.131T>C(p.Ile44Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,459,070 control chromosomes in the GnomAD database, with no homozygous occurrence. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I44R) has been classified as Benign.

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.

The c.131T>C (p.I44T) alteration is located in exon 2 (coding exon 2) of the ADAMDEC1 gene. This alteration results from a T to C substitution at nucleotide position 131, causing the isoleucine (I) at amino acid position 44 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
