Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.154C>T (p.L52F) alteration is located in exon 2 (coding exon 1) of the TBC1D14 gene. This alteration results from a C to T substitution at nucleotide position 154, causing the leucine (L) at amino acid position 52 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
