Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.277T>G (p.L93V) alteration is located in exon 3 (coding exon 3) of the PLGLB2 gene. This alteration results from a T to G substitution at nucleotide position 277, causing the leucine (L) at amino acid position 93 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
