Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.196T>G (p.W66G) alteration is located in exon 2 (coding exon 2) of the VSTM2B gene. This alteration results from a T to G substitution at nucleotide position 196, causing the tryptophan (W) at amino acid position 66 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
