Genes affected

SIGLEC10 (HGNC:15620): (sialic acid binding Ig like lectin 10) SIGLECs are members of the immunoglobulin superfamily that are expressed on the cell surface. Most SIGLECs have 1 or more cytoplasmic immune receptor tyrosine-based inhibitory motifs, or ITIMs. SIGLECs are typically expressed on cells of the innate immune system, with the exception of the B-cell expressed SIGLEC6 (MIM 604405).[supplied by OMIM, Jul 2002]

The c.1861C>G (p.R621G) alteration is located in exon 11 (coding exon 11) of the SIGLEC10 gene. This alteration results from a C to G substitution at nucleotide position 1861, causing the arginine (R) at amino acid position 621 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
