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]

The c.1270G>T (p.A424S) alteration is located in exon 15 (coding exon 12) of the EOGT gene. This alteration results from a G to T substitution at nucleotide position 1270, causing the alanine (A) at amino acid position 424 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
