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]

SIGLEC15 links:

EPG5 (HGNC:29331): (ectopic P-granules 5 autophagy tethering factor) This gene encodes a large coiled coil domain-containing protein that functions in autophagy during starvation conditions. Mutations in this gene cause Vici syndrome. [provided by RefSeq, Aug 2015]

Ambry Genetics

Jan 03, 2024

The c.185T>G (p.L62R) alteration is located in exon 3 (coding exon 3) of the SIGLEC15 gene. This alteration results from a T to G substitution at nucleotide position 185, causing the leucine (L) at amino acid position 62 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
