Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2PP2BP4_Strong
The ENST00000269571.10(ERBB2):c.3427C>A(p.Pro1143Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000219 in 1,554,524 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. P1143L) has been classified as Uncertain significance.

not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Sep 26, 2023 | This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1143 of the ERBB2 protein (p.Pro1143Thr). This variant is present in population databases (rs587778268, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with ERBB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 134080). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
