Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 02, 2023The c.643T>G (p.L215V) alteration is located in exon 3 (coding exon 3) of the TBPL2 gene. This alteration results from a T to G substitution at nucleotide position 643, causing the leucine (L) at amino acid position 215 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
