Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 03, 2023The c.1223T>C (p.L408P) alteration is located in exon 3 (coding exon 3) of the IRX2 gene. This alteration results from a T to C substitution at nucleotide position 1223, causing the leucine (L) at amino acid position 408 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
