Invitae	RCV000048301	SCV000076314	pathogenic	Hereditary breast ovarian cancer syndrome	2023-06-23	criteria provided, single submitter	clinical testing	This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln1240*) in the BRCA1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRCA1 are known to be pathogenic (PMID: 20104584). This premature translational stop signal has been observed in individual(s) with breast, ovarian, and endometrial cancer (PMID: 17645508, 22923021, 24333842, 25480878, 27393621). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 54978). This variant is also known as 3837C>T.
Ambry Genetics	RCV000162866	SCV000213353	pathogenic	Hereditary cancer-predisposing syndrome	2022-07-12	criteria provided, single submitter	clinical testing	The p.Q1240* pathogenic mutation (also known as c.3718C>T) located in coding exon 9 of the BRCA1 gene, results from a C to T substitution at nucleotide position 3718. This changes the amino acid from a glutamine to a stop codon within coding exon 9. This mutation has been reported in many individuals with personal and family histories of breast, ovarian, fallopian tube, and prostate cancer (Callahan MJ et al. J. Clin. Oncol. 2007 Sep;25:3985-90; Novakovi S et al. Int. J. Oncol. 2012 Nov;41:1619-27; Connor JR et al. Gynecol. Oncol. 2014 Feb;132:280-6; Wang C et al. Ann. Oncol. 2015 Mar;26:523-8; Zhang J et al. Breast Cancer Res. Treat. 2016 Aug;158:455-62; Cvelbar M et al. Radiol. Oncol. 2017 Jun;51(2):187-194). It has also been reported in a female patient diagnosed with advanced metastatic endometrial cancer who had a family history of melanoma, breast cancer, and prostate cancer (Kwon JS et al. Int. J. Gynecol. Cancer. 2008 May-Jun;18:546-9). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Of note, this alteration is also designated as 3837C>T and Q1240X in published literature. In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000048301	SCV000271317	pathogenic	Hereditary breast ovarian cancer syndrome	2015-07-29	criteria provided, single submitter	clinical testing	The p.Gln1240X variant in BRCA1 has been reported in 2 individuals with endometr ial cancer (Kwon 2008, Conner 2014) and at least 7 individuals with breast and/o r ovarian cancer (Novakovic 2012, Wang 2015, Breast Cancer Information Core (BIC )). It was absent from large population studies. This nonsense variant leads to a premature termination codon at position 1240, which is predicted to lead to a truncated or absent protein. Heterozygous loss of BRCA1 function is an establish ed disease mechanism in hereditary breast and ovarian cancer (HBOC). In summary, this variant meets our criteria to be classified as pathogenic for HBOC in an a utosomal dominant manner (http://www.partners.org/personalizedmedicine/LMM) base d upon the predicted impact to the protein, presence in affected individuals, an d absence in controls.
