Genes affected

CD300A (HGNC:19319): (CD300a molecule) This gene encodes a member of the CD300 glycoprotein family of cell surface proteins found on leukocytes involved in immune response signaling pathways. This gene is located on chromosome 17 in a cluster with all but one of the other family members. Multiple transcript variants encoding different isoforms have been found for this gene.

May 13, 2024

The c.37C>G (p.P13A) alteration is located in exon 1 (coding exon 1) of the CD300A gene. This alteration results from a C to G substitution at nucleotide position 37, causing the proline (P) at amino acid position 13 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
