Genes affected
CD300E (HGNC:28874): (CD300e molecule) This gene encodes a member of the CD300 glycoprotein family of cell surface proteins expressed on myeloid cells. The protein interacts with the TYRO protein tyrosine kinase-binding protein and is thought to act as an activating receptor. [provided by RefSeq, Nov 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2023The c.450C>A (p.N150K) alteration is located in exon 3 (coding exon 3) of the CD300E gene. This alteration results from a C to A substitution at nucleotide position 450, causing the asparagine (N) at amino acid position 150 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
