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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.530C>T (p.T177I) alteration is located in exon 4 (coding exon 4) of the CD300LG gene. This alteration results from a C to T substitution at nucleotide position 530, causing the threonine (T) at amino acid position 177 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
