Genes affected
GLMN (HGNC:14373): (glomulin, FKBP associated protein) This gene encodes a phosphorylated protein that is a member of a Skp1-Cullin-F-box-like complex. The protein is essential for normal development of the vasculature and mutations in this gene have been associated with glomuvenous malformations, also called glomangiomas. Multiple splice variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0364 CDS is truncated, and there are 1 pathogenic variants in the truncated region.
PP5
Variant 1-92246595-G-A is Pathogenic according to our data. Variant chr1-92246595-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 618145.Status of the report is criteria_provided_single_submitter, 1 stars.
BS2
High AC in GnomAdExome4 at 13 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Likely pathogenic, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesMay 13, 2018The GLMN: p.Arg574Ter variant (rs751408583) was reported in one patient with glomuvenous malformation (Brouillard 2013). This variant is listed in the Genome Aggregation Database (gnomAD) identified on a single chromosome out of 245,592. This variant results in a premature termination codon in the last exon of the GLMN gene. While this may not lead to nonsense-mediated decay, it is expected to create a truncated protein product. Nonsense variants in GLMN are a common mechanism of disease. Based on the above, the p.Arg574Ter variant is considered to be likely pathogenic. -
