Sep 05, 2024

The c.347C>T (p.P116L) alteration is located in exon 4 (coding exon 3) of the HMGXB3 gene. This alteration results from a C to T substitution at nucleotide position 347, causing the proline (P) at amino acid position 116 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
