Genes affected
EOGT (HGNC:28526): (EGF domain specific O-linked N-acetylglucosamine transferase) This gene encodes an enzyme that acts in the lumen of the endoplasmic reticulum to catalyze the transfer of N-acetylglucosamine to serine or threonine residues of extracellular-targeted proteins. This enzyme modifies proteins containing eukaryotic growth factor (EGF)-like domains, including the Notch receptor, thereby regulating developmental signalling. Mutations in this gene have been observed in individuals with Adams-Oliver syndrome 4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.06376263 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.6, offset of -39, new splice context is: cagGTttgg. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PP5
Variant 3-69008427-C-A is Pathogenic according to our data. Variant chr3-69008427-C-A is described in ClinVar as Pathogenic. ClinVar VariationId is 523579.Status of the report is criteria_provided_single_submitter, 1 stars.
