Genes affected
C2CD2L (HGNC:29000): (C2CD2 like) Enables phosphatidylinositol binding activity and phosphatidylinositol transfer activity. Involved in positive regulation of insulin secretion involved in cellular response to glucose stimulus. Located in cortical endoplasmic reticulum and endoplasmic reticulum-plasma membrane contact site. Colocalizes with cytoplasmic side of apical plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
DPAGT1 (HGNC:2995): (dolichyl-phosphate N-acetylglucosaminephosphotransferase 1) The protein encoded by this gene is an enzyme that catalyzes the first step in the dolichol-linked oligosaccharide pathway for glycoprotein biosynthesis. This enzyme belongs to the glycosyltransferase family 4. This protein is an integral membrane protein of the endoplasmic reticulum. The congenital disorder of glycosylation type Ij is caused by mutation in the gene encoding this enzyme. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2024The c.28G>T (p.V10L) alteration is located in exon 1 (coding exon 1) of the C2CD2L gene. This alteration results from a G to T substitution at nucleotide position 28, causing the valine (V) at amino acid position 10 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
