NM_024675.4:c.3024C>T
Variant summary
Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6_Very_StrongBP7
The NM_024675.4(PALB2):c.3024C>T(p.Pro1008Pro) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,613,774 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 Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. P1008P) has been classified as Likely benign.

Submissions by phenotype
Familial cancer of breast Benign:3
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
Curators: Marc Tischkowitz, Arleen D. Auerbach. Submitters to LOVD: Marc Tischkowitz, Yukihide Momozawa. -

Hereditary cancer-predisposing syndrome Benign:2
- -
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Malignant tumor of breast Benign:1
The PALB2 p.Pro1008= variant was identified in 9 of 14234 proband chromosomes (frequency: 0.0006) from Italian families and Japanese women with breast cancer and was present in 15 of 11391 control chromosomes (frequency: 001) from healthy individuals (Papi 2010, Momozawa 2018). The variant was also identified in dbSNP (ID: rs180177130) as “With Likely benign allele”, ClinVar (4x as likely benign by Invitae, Ambry Genetics, Color, PALB2 database), LOVD 3.0 (4x as benign). The variant was identified in control databases in 1 of 246232 chromosomes at a frequency of 0.000004 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: East Asian in 1 of 17248 chromosomes (freq: 0.00006), while the variant was not observed in the African, Other, Latino, European Non-Finnish, Ashkenazi Jewish, European Finnish or South Asian populations. The p.Pro1008= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
