Genes affected

LRRC15 (HGNC:20818): (leucine rich repeat containing 15) Enables collagen binding activity; fibronectin binding activity; and laminin binding activity. Involved in negative regulation of protein localization to plasma membrane; positive regulation of cell migration; and receptor-mediated virion attachment to host cell. Located in extracellular exosome. Colocalizes with collagen-containing extracellular matrix. [provided by Alliance of Genome Resources, Apr 2022]

The c.1179C>A (p.N393K) alteration is located in exon 3 (coding exon 2) of the LRRC15 gene. This alteration results from a C to A substitution at nucleotide position 1179, causing the asparagine (N) at amino acid position 393 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
