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.

Ambry Genetics

Feb 23, 2023

The c.70G>A (p.V24M) alteration is located in exon 2 (coding exon 2) of the CD300A gene. This alteration results from a G to A substitution at nucleotide position 70, causing the valine (V) at amino acid position 24 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
