Collection Method: clinical testing

The c.37T>C (p.Y13H) alteration is located in exon 2 (coding exon 1) of the BCL6B gene. This alteration results from a T to C substitution at nucleotide position 37, causing the tyrosine (Y) at amino acid position 13 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
