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 GeneticsMay 25, 2022The c.607A>G (p.M203V) alteration is located in exon 4 (coding exon 4) of the CD300A gene. This alteration results from a A to G substitution at nucleotide position 607, causing the methionine (M) at amino acid position 203 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
