Genetic Variant CDCP2:p.Arg288His (chr1-54140007-C-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001353655.3(CDCP2):c.863G>A(p.Arg288His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000595 in 1,613,980 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. R288C) has been classified as Uncertain significance.

The c.863G>A (p.R288H) alteration is located in exon 4 (coding exon 4) of the CDCP2 gene. This alteration results from a G to A substitution at nucleotide position 863, causing the arginine (R) at amino acid position 288 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
