Genes affected

CD300LF (HGNC:29883): (CD300 molecule like family member f) This gene encodes a member of the CD300 protein family. Members of this family are cell surface glycoproteins with a single IgV-like extracellular domain, and are involved in the regulation of immune response. The encoded protein is an inhibitory receptor. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

CD300LF links:

RAB37 (HGNC:30268): (RAB37, member RAS oncogene family) Rab proteins are low molecular mass GTPases that are critical regulators of vesicle trafficking. For additional background information on Rab proteins, see MIM 179508.[supplied by OMIM, Apr 2006]

The c.649C>A (p.P217T) alteration is located in exon 6 (coding exon 6) of the CD300LF gene. This alteration results from a C to A substitution at nucleotide position 649, causing the proline (P) at amino acid position 217 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
