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.

Generalized juvenile polyposis/juvenile polyposis coli Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 25, 2018 | This variant is a gross deletion of the genomic region encompassing the promoter (non-coding exon 1) of the BMPR1A gene. The 5' end of this event is unknown as it extends beyond the assayed region for this gene, and therefore may encompass additional genes. The 3' boundary is likely confined to the region between non-coding exon 1 and non-coding exon 2. A large genomic deletion involving the promoter region (non-coding exon 1) has been reported to segregate with BMPR1A-related disease in a family (PMID: 20843829). A similar deletion involving the promoter region has also been reported in an individual with congenital heart defect who was pending for juvenile polyposis screening (PMID: 22067610). Experimental studies have shown that deletion of this promoter region impairs the transcription of a reporter gene in vitro, and protein samples derived from individuals carrying this variant showed reduced BMPR1A protein levels compared to a control sample (PMID: 20843829, 21872883). For these reasons, this variant has been classified as Pathogenic. - |
