Genes affected
BMPR1A (HGNC:1076): (bone morphogenetic protein receptor type 1A) The bone morphogenetic protein (BMP) receptors are a family of transmembrane serine/threonine kinases that include the type I receptors BMPR1A and BMPR1B and the type II receptor BMPR2. These receptors are also closely related to the activin receptors, ACVR1 and ACVR2. The ligands of these receptors are members of the TGF-beta superfamily. TGF-betas and activins transduce their signals through the formation of heteromeric complexes with 2 different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Type II receptors bind ligands in the absence of type I receptors, but they require their respective type I receptors for signaling, whereas type I receptors require their respective type II receptors for ligand binding.

The splice region variant NM_004329.3(BMPR1A):c.1342+6A>G has been reported to ClinVar as Benign with a status of (2 stars) criteria provided, multiple submitters, no conflicts (Variation ID 301352 as of 2025-01-02).The c.1342+6A>G variant is observed in 130/5,008 (2.5958%) alleles from individuals of 1kG All background in 1kG, indicating it is a common benign variant. The c.1342+6A>G variant is not predicted to disrupt the existing donor splice site 4bp upstream by any splice site algorithm. The c.1342+6A>G variant results in a substitution of a base that is not predicted conserved by GERP++ and PhyloP. For these reasons, this variant has been classified as Benign. -

The BMPR1A c.1342+6A>G was identified in dbSNP (ID: rs55763614) as “With Likely benign allele”, and ClinVar (classified as benign by Invitae, Quest Diagnostics Nichols Institute San Juan Capistrano, Color, Prevention Genetics and Mayo Clinic Genetic Testing Laboratories; and likely benign by Illumina). The variant was identified in control databases in 2067 (75 homozygous) of 277240 chromosomes at a frequency of 0.007 (Genome Aggregation Database Feb 27, 2017), observed in the following populations: African in 1906 (75 homozygous) of 24032 chromosomes (freq: 0.08), Other in 18 of 6466 chromosomes (freq: 0.003), Latino in 118 of 34418 chromosomes (freq: 0.003), European Non-Finnish in 22 of 126728 chromosomes (freq: 0.0002), and South Asian in 3 of 30780 chromosomes (freq: 0.0001), while not observed in the Ashkenazi Jewish, East Asian, and European Finnish populations. The c.1342+6A>G variant is located in the 5' splice region but does not affect the invariant +1 and +2 positions. However, positions +3 to +6 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing. 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 this variant meets our laboratory's criteria to be classified as benign. -

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
