Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001349074.2(TBC1D5):ā€‹c.2117G>Cā€‹(p.Arg706Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,613,872 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R706Q) has been classified as Uncertain significance.

Genes affected
TBC1D5 (HGNC:19166): (TBC1 domain family member 5) Enables AP-2 adaptor complex binding activity and retromer complex binding activity. Involved in several processes, including macroautophagy; positive regulation of receptor internalization; and retrograde transport, endosome to Golgi. Located in Golgi apparatus; autophagosome; and endosome membrane. Part of retromer complex. Colocalizes with AP-2 adaptor complex and Atg1/ULK1 kinase complex.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.2117G>C (p.R706P) alteration is located in exon 23 (coding exon 20) of the TBC1D5 gene. This alteration results from a G to C substitution at nucleotide position 2117, causing the arginine (R) at amino acid position 706 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
