Variant summary
Our verdict is Benign. The variant received -18 ACMG points: 0P and 18B. BP4_ModerateBP6_Very_StrongBS1BS2
The NM_004329.3(BMPR1A):c.961C>T(p.Leu321Leu) variant causes a synonymous change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000948 in 1,613,838 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. L321L) has been classified as Likely benign.

Submissions by phenotype
not specified Benign:3
- -
- -
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
not provided Benign:3
The BMPR1A c.961C>T; p.Leu321Leu variant (rs377412651), to our knowledge, is not reported in the medical literature but is reported as benign or likely benign in ClinVar (Variation ID: 184634). This variant is observed in the general population with an overall allele frequency of 0.02% (55/276926 alleles) in the Genome Aggregation Database. This is a synonymous change and computational algorithms do not predict this variant to impact splicing (Alamut v.2.10). Based on available information, this variant is considered likely benign. -
- -
Variant summary: The BMPR1A c.961C>T (p.Leu321Leu) variant involves the alteration of a conserved nucleotide causing a synonymous change and 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may create an ESE binding site. However, these predictions have yet to be confirmed by functional studies. This variant was found in 55/276926 control chromosomes at a frequency of 0.0001986, which is approximately 99 times the estimated maximal expected allele frequency of a pathogenic BMPR1A variant (0.000002), suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign/benign. Taken together, this variant is classified as benign. -
Hereditary cancer-predisposing syndrome Benign:3
- -
- -
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. -
Juvenile polyposis syndrome Benign:2
- -
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
BMPR1A-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Familial colorectal cancer type X Benign:1
- -
Generalized juvenile polyposis/juvenile polyposis coli Benign:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
