Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate
The NM_004329.3(BMPR1A):c.5C>G(p.Pro2Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,184 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P2L) has been classified as Uncertain significance.

Submissions by phenotype
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Jun 27, 2023 | This missense variant replaces proline with arginine at codon 2 of the BMPR1A protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with BMPR1A-related disorders in the literature. This variant has been identified in 2/282724 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
Juvenile polyposis syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 24, 2021 | This variant has not been reported in the literature in individuals affected with BMPR1A-related conditions. This variant is present in population databases (rs143248687, gnomAD 0.002%). This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 2 of the BMPR1A protein (p.Pro2Arg). 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 not expected to disrupt BMPR1A protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
