Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 2P and 7B. PM2BP4_ModerateBP6BS1
The NM_001843.4(CNTN1):āc.1280C>Gā(p.Ala427Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000434 in 1,613,762 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. A427A) has been classified as Likely benign.
