Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.307G>A (p.V103I) alteration is located in exon 4 (coding exon 4) of the VSTM2A gene. This alteration results from a G to A substitution at nucleotide position 307, causing the valine (V) at amino acid position 103 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
