Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.181C>A (p.L61I) alteration is located in exon 3 (coding exon 3) of the TBC1D17 gene. This alteration results from a C to A substitution at nucleotide position 181, causing the leucine (L) at amino acid position 61 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
