Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.46G>T (p.V16F) alteration is located in exon 1 (coding exon 1) of the VSTM2A gene. This alteration results from a G to T substitution at nucleotide position 46, causing the valine (V) at amino acid position 16 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
