Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.241C>T (p.L81F) alteration is located in exon 2 (coding exon 2) of the VSTM2B gene. This alteration results from a C to T substitution at nucleotide position 241, causing the leucine (L) at amino acid position 81 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
