Variant summary
Our verdict is Pathogenic. Variant got 13 ACMG points: 13P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Moderate
The NM_004329.3(BMPR1A):c.370T>A(p.Cys124Ser) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C124R) has been classified as Pathogenic.

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.

Juvenile polyposis syndrome Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jun 24, 2021 | This variant is not present in population databases (ExAC no frequency). This sequence change replaces cysteine with serine at codon 124 of the BMPR1A protein (p.Cys124Ser). The cysteine residue is highly conserved and there is a moderate physicochemical difference between cysteine and serine. This variant has been observed in individual(s) with clinical features of juvenile polyposis syndrome (Invitae). ClinVar contains an entry for this variant (Variation ID: 665840). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt BMPR1A protein function. - |
