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]

Collection Method: clinical testing

The c.1637C>T (p.T546M) alteration is located in exon 9 (coding exon 9) of the SIGLEC10 gene. This alteration results from a C to T substitution at nucleotide position 1637, causing the threonine (T) at amino acid position 546 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
