Genes affected

CDON (HGNC:17104): (cell adhesion associated, oncogene regulated) This gene encodes a cell surface receptor that is a member of the immunoglobulin superfamily. The encoded protein contains three fibronectin type III domains and five immunoglobulin-like C2-type domains. This protein is a member of a cell-surface receptor complex that mediates cell-cell interactions between muscle precursor cells and positively regulates myogenesis. [provided by RefSeq, Aug 2011]

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 11-125961806-G-A is Benign according to our data. Variant chr11-125961806-G-A is described in ClinVar as [Benign]. Clinvar id is 260797.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-125961806-G-A is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-0.053 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.309 is higher than 0.05.

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
