Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_020770.3(CGN):c.479C>T(p.Ala160Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000242 in 1,614,088 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/18 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. A160T) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.479C>T (p.A160V) alteration is located in exon 2 (coding exon 1) of the CGN gene. This alteration results from a C to T substitution at nucleotide position 479, causing the alanine (A) at amino acid position 160 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
