Variant summary
Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2BP4_StrongBP6
The NM_024675.4(PALB2):c.48+5C>T variant causes a splice donor 5th base, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,460,968 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 18, 2023 | The c.48+5C>T intronic variant results from a C to T substitution 5 nucleotides after coding exon 1 in the PALB2 gene. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
