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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 11, 2023The c.293C>T (p.A98V) alteration is located in exon 3 (coding exon 3) of the SIGLEC15 gene. This alteration results from a C to T substitution at nucleotide position 293, causing the alanine (A) at amino acid position 98 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
