Genes affected

SIGLEC15 (HGNC:27596): (sialic acid binding Ig like lectin 15) Predicted to be involved in regulation of actin cytoskeleton organization; regulation of bone resorption; and regulation of osteoclast development. Predicted to be integral component of membrane. Predicted to be part of protein-containing complex. Predicted to be active in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

May 31, 2023

The c.113G>T (p.S38I) alteration is located in exon 3 (coding exon 3) of the SIGLEC15 gene. This alteration results from a G to T substitution at nucleotide position 113, causing the serine (S) at amino acid position 38 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
