Genes affected

SIGLEC6 (HGNC:10875): (sialic acid binding Ig like lectin 6) This gene encodes a member of the SIGLEC (sialic acid binding immunoglobulin-like lectin) family of proteins. The encoded transmembrane receptor binds sialyl-TN glycans and leptin. Placental expression of the encoded protein is upregulated in preeclampsia. [provided by RefSeq, Jul 2016]

The c.310T>C (p.C104R) alteration is located in exon 2 (coding exon 2) of the SIGLEC6 gene. This alteration results from a T to C substitution at nucleotide position 310, causing the cysteine (C) at amino acid position 104 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
