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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2023The c.88G>A (p.G30R) 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 88, causing the glycine (G) at amino acid position 30 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
