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]

Jul 05, 2023

The c.148T>C (p.C50R) alteration is located in exon 2 (coding exon 2) of the CD300E gene. This alteration results from a T to C substitution at nucleotide position 148, causing the cysteine (C) at amino acid position 50 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
