Genes affected

SIGLEC11 (HGNC:15622): (sialic acid binding Ig like lectin 11) This gene encodes a member of the sialic acid-binding immunoglobulin-like lectin family. These cell surface lectins are characterized by structural motifs in the immunoglobulin (Ig)-like domains and sialic acid recognition sites in the first Ig V set domain. This family member mediates anti-inflammatory and immunosuppressive signaling. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.1877C>T (p.P626L) alteration is located in exon 11 (coding exon 11) of the SIGLEC11 gene. This alteration results from a C to T substitution at nucleotide position 1877, causing the proline (P) at amino acid position 626 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
