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.

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.51).
• BP6: Variant 10-86923452-T-G is Benign according to our data. Variant chr10-86923452-T-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 136526.
• BP7: Synonymous conserved (PhyloP=0.112 with no splicing effect.
• BS1: Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000578 (88/152314) while in subpopulation AMR AF = 0.000458 (7/15292). AF 95% confidence interval is 0.000215. There are 0 homozygotes in GnomAd4. There are 40 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 88 AD,Unknown gene.
