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

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 2-202376545-G-GGCA is Benign according to our data. Variant chr2-202376545-G-GGCA is described in ClinVar as [Likely_benign]. Clinvar id is 333620.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.00378 (532/140572) while in subpopulation AMR AF= 0.0279 (372/13352). AF 95% confidence interval is 0.0255. There are 13 homozygotes in gnomad4. There are 298 alleles in male gnomad4 subpopulation. Median coverage is 26. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 532 AD gene.
