Jul 14, 2021

The c.230C>T (p.P77L) alteration is located in exon 2 (coding exon 2) of the TBPL2 gene. This alteration results from a C to T substitution at nucleotide position 230, causing the proline (P) at amino acid position 77 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
