The c.101T>C (p.L34P) alteration is located in exon 1 (coding exon 1) of the DBX2 gene. This alteration results from a T to C substitution at nucleotide position 101, causing the leucine (L) at amino acid position 34 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
