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

Verdict is Pathogenic. Variant got 16 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PP5: Variant 1-92297461-G-T is Pathogenic according to our data. Variant chr1-92297461-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 523551.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
