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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.64C>G (p.L22V) alteration is located in exon 1 (coding exon 1) of the MRC2 gene. This alteration results from a C to G substitution at nucleotide position 64, causing the leucine (L) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
