Genes affected

NT5DC2 (HGNC:25717): (5'-nucleotidase domain containing 2) Predicted to enable 5'-nucleotidase activity. Predicted to be involved in dephosphorylation. [provided by Alliance of Genome Resources, Apr 2022]

NT5DC2 links:

STAB1 (HGNC:18628): (stabilin 1) This gene encodes a large, transmembrane receptor protein which may function in angiogenesis, lymphocyte homing, cell adhesion, or receptor scavenging. The protein contains 7 fasciclin, 16 epidermal growth factor (EGF)-like, and 2 laminin-type EGF-like domains as well as a C-type lectin-like hyaluronan-binding Link module. The protein is primarily expressed on sinusoidal endothelial cells of liver, spleen, and lymph node. The receptor has been shown to endocytose ligands such as low density lipoprotein, Gram-positive and Gram-negative bacteria, and advanced glycosylation end products. Supporting its possible role as a scavenger receptor, the protein rapidly cycles between the plasma membrane and early endosomes. [provided by RefSeq, Jul 2008]

The c.1669C>T (p.R557C) alteration is located in exon 14 (coding exon 14) of the NT5DC2 gene. This alteration results from a C to T substitution at nucleotide position 1669, causing the arginine (R) at amino acid position 557 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
