Genes affected

SIGLEC14 (HGNC:32926): (sialic acid binding Ig like lectin 14) Predicted to enable sialic acid binding activity. Predicted to be involved in cell adhesion. Predicted to be located in ficolin-1-rich granule membrane and tertiary granule membrane. Predicted to be active in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

SIGLEC14 links:

SIGLEC5 (HGNC:10874): (sialic acid binding Ig like lectin 5) This gene encodes a member of the sialic acid-binding immunoglobulin-like lectin (Siglec) 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. The encoded protein is a member of the CD33-related subset of Siglecs and inhibits the activation of several cell types including monocytes, macrophages and neutrophils. Binding of group B Streptococcus (GBS) to the encoded protein plays a role in GBS immune evasion. [provided by RefSeq, Feb 2012]

Collection Method: clinical testing

The c.858G>T (p.W286C) alteration is located in exon 5 (coding exon 5) of the SIGLEC14 gene. This alteration results from a G to T substitution at nucleotide position 858, causing the tryptophan (W) at amino acid position 286 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
