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 Pathogenic. Variant got 15 ACMG points.

PVS1
Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
PP5
Variant 1-92263708-T-TA is Pathogenic according to our data. Variant chr1-92263708-T-TA is described in ClinVar as [Likely_pathogenic]. Clinvar id is 660874.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS2
High AC in GnomAd4 at 21 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 25, 2018Loss-of-function variants in GLMN are known to be pathogenic (PMID: 23801931). This variant has been observed in an individual affected with vascular anomalies (PMID: 28655553). This variant is present in population databases (rs771252983, ExAC 0.06%). This sequence change creates a premature translational stop signal (p.Thr442Tyrfs*10) in the GLMN gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. -
