dbSNP rs140592056: BMPR1A:p.Glu415Lys (chr10-86921596-G-A) – ACMG Classification: Benign (-12 pts)

Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 1P and 13B. PP3BP4_StrongBP6BS1BS2

The NM_004329.3(BMPR1A):c.1243G>A(p.Glu415Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000493 in 1,614,142 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E415D) has been classified as Uncertain significance.

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

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 9: BayesDel_addAF, BayesDel_noAF, Cadd, Dann, Eigen, phyloP100way_vertebrate, PrimateAI, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationAssessor, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.03156662).

BP6

Variant 10-86921596-G-A is Benign according to our data. Variant chr10-86921596-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 41779.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000545 (83/152272) while in subpopulation AMR AF = 0.00072 (11/15286). AF 95% confidence interval is 0.000403. There are 2 homozygotes in GnomAd4. There are 41 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 83 Unknown,AD gene.
