Genes affected

CD300LG (HGNC:30455): (CD300 molecule like family member g) Members of the CD300 (see MIM 606786)-like (CD300L) family, such as CD300LG, are widely expressed on hematopoietic cells. All CD300L proteins are type I cell surface glycoproteins that contain a single immunoglobulin (Ig) V-like domain (Takatsu et al., 2006 [PubMed 16876123]).[supplied by OMIM, Mar 2008]

The c.740G>A (p.R247H) alteration is located in exon 5 (coding exon 5) of the CD300LG gene. This alteration results from a G to A substitution at nucleotide position 740, causing the arginine (R) at amino acid position 247 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
