Genes affected

MRC2 (HGNC:16875): (mannose receptor C type 2) This gene encodes a member of the mannose receptor family of proteins that contain a fibronectin type II domain and multiple C-type lectin-like domains. The encoded protein plays a role in extracellular matrix remodeling by mediating the internalization and lysosomal degradation of collagen ligands. Expression of this gene may play a role in the tumorigenesis and metastasis of several malignancies including breast cancer, gliomas and metastatic bone disease. [provided by RefSeq, Feb 2012]

Jan 23, 2024

The c.213C>A (p.S71R) alteration is located in exon 2 (coding exon 2) of the MRC2 gene. This alteration results from a C to A substitution at nucleotide position 213, causing the serine (S) at amino acid position 71 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
