• NM_001127173.3:c.50G>C

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 3P and 2B. PM2 PP2 BP4_Moderate

The NM_001127173.3(CADM3):​c.50G>C​(p.Cys17Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000000913 in 1,094,922 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C17Y) has been classified as Uncertain significance.

Genes affected

CADM3 (HGNC:17601): (cell adhesion molecule 3) The protein encoded by this gene is a calcium-independent cell-cell adhesion protein that can form homodimers or heterodimers with other nectin proteins. The encoded protein has both homophilic and heterophilic cell-cell adhesion activity. This gene is reported to be a tumor suppressor gene. [provided by RefSeq, Oct 2016]

AIM2 (HGNC:357): (absent in melanoma 2) AIM2 is a member of the IFI20X /IFI16 family. It plays a putative role in tumorigenic reversion and may control cell proliferation. Interferon-gamma induces expression of AIM2. [provided by RefSeq, Jul 2008]

CADM3-AS1 (HGNC:40812): (CADM3 antisense RNA 1)

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.6917 (below the threshold of 3.09). Trascript score misZ: 1.5575 (below the threshold of 3.09). GenCC associations: The gene is linked to Charcot-Marie-Tooth disease, axonal, type 2FF.
• BP4: Computational evidence support a benign effect (MetaRNN=0.24907342).
