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]

Review Status:reviewed by expert panel

Collection Method:curation

NM_001204.7(BMPR2):c.1284C>T (p.Ser428Ser) The BMPR2 c.1284C>T variant is a synonymous (silent) variant that is not predicted by SpliceAI to impact splicing.The highest population minor allele frequency in gnomAD v2.1.1 controls is 0.072% (3/4154 alleles) in the Estonian population, which is lower than the ClinGen Pulmonary Hypertension VCEP threshold of >0.1% for BS1 and >1% for BA1, and higher than the ClinGen Pulmonary Hypertension VCEP threshold of <0.01% for PM2. Neither BS1, BA1 nor PM2 are met. BS2 was not met as the variant was not observed as a homozygous allele in gnomAD v2.1.1 controls. Neither BP4 nor PP3 were met based on the computational predictor, CADD, giving a score of 11.4 which is above the threshold of <=10.0 for BP4 and below the threshold of >=20 for PP3. Due to the absence of segregation data PP1, PM6 and PS2 could not be evaluated. Due to absence of functional data PS3 could not be evaluated. In summary, the variant meets the criteria to be classified as a variant of uncertain significance for pulmonary arterial hypertension based on the ACMG/AMP criteria applied, as specified by the ClinGen Pulmonary Hypertension VCEP: BP7 (VCEP specification version 1.1, 1/18/2024).

Significance:Uncertain significance

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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
