Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_024675.4(PALB2):c.706T>G(p.Phe236Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,174 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 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. F236I) has been classified as Uncertain significance.

Submissions by phenotype
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 18, 2021 | The c.706T>G (p.F236V) alteration is located in exon 4 (coding exon 4) of the PALB2 gene. This alteration results from a T to G substitution at nucleotide position 706, causing the phenylalanine (F) at amino acid position 236 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
Familial cancer of breast Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 11, 2022 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 826817). This variant has not been reported in the literature in individuals affected with PALB2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces phenylalanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 236 of the PALB2 protein (p.Phe236Val). - |
