Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM1BP4_StrongBP6
The NM_007294.4(BRCA1):c.4410A>T(p.Glu1470Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000285 in 1,613,734 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. E1470E) has been classified as Likely benign.

This alteration is classified as 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. -

Variant summary: BRCA1 c.4410A>T (p.Glu1470Asp) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 251242 control chromosomes, predominantly at a frequency of 8.7e-05 within the Latino subpopulation in the gnomAD database. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.4410A>T has been reported in the literature in individuals with a personal and/or family history of breast/ovarian cancers (examples : Judkins_2005, Borg_2010, Dutil_2012, Diaz-Zabala_2018, Matta_2022). However, these reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Co-occurrences with the same pathogenic variant have been reported in 3 separate individuals (BRCA2 c.3922G>T, p.Glu1308X; NHGRI BIC and internal testing), providing supporting evidence for a benign role. At least two publications report experimental evidence evaluating an impact on protein function. These results showed no damaging effect of this variant (example, Woods_2016, Fernandes_2019, Nepomuceno_2022). The following publications have been ascertained in the context of this evaluation (PMID: 24728327, 20104584, 21520273, 30400234, 22682623, 30765603, 27843123, 16267036, 36329109, 36171434, 30212499, 28781887). ClinVar contains an entry for this variant (Variation ID: 89064). Based on the evidence outlined above, the variant was classified as likely benign. -
