Genes affected

BMPR2 (HGNC:1078): (bone morphogenetic protein receptor type 2) This gene encodes a member of the bone morphogenetic protein (BMP) receptor family of transmembrane serine/threonine kinases. The ligands of this receptor are members of the TGF-beta superfamily. BMPs are involved in endochondral bone formation and embryogenesis. These proteins transduce their signals through the formation of heteromeric complexes of two different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Mutations in this gene have been associated with primary pulmonary hypertension, both familial and fenfluramine-associated, and with pulmonary venoocclusive disease. [provided by RefSeq, May 2020]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BP6: Variant 2-202376548-A-G is Benign according to our data. Variant chr2-202376548-A-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 333622.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0059 (692/117236) while in subpopulation AFR AF = 0.0166 (547/33018). AF 95% confidence interval is 0.0154. There are 2 homozygotes in GnomAd4. There are 335 alleles in the male GnomAd4 subpopulation. Median coverage is 24. This position passed quality control check.
• BS2: High AC in GnomAd4 at 692 AD gene.
