Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.119T>A (p.L40H) alteration is located in exon 2 (coding exon 1) of the TBC1D14 gene. This alteration results from a T to A substitution at nucleotide position 119, causing the leucine (L) at amino acid position 40 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
