Genes affected

TBC1D17 (HGNC:25699): (TBC1 domain family member 17) Predicted to enable GTPase activator activity. Involved in retrograde transport, endosome to Golgi. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

TBC1D17 links:

AKT1S1 (HGNC:28426): (AKT1 substrate 1) AKT1S1 is a proline-rich substrate of AKT (MIM 164730) that binds 14-3-3 protein (see YWHAH, MIM 113508) when phosphorylated (Kovacina et al., 2003 [PubMed 12524439]).[supplied by OMIM, Mar 2008]

AKT1S1 links:

PNKP (HGNC:9154): (polynucleotide kinase 3'-phosphatase) This locus represents a gene involved in DNA repair. In response to ionizing radiation or oxidative damage, the protein encoded by this locus catalyzes 5' phosphorylation and 3' dephosphorylation of nucleic acids. Mutations at this locus have been associated with microcephaly, seizures, and developmental delay.[provided by RefSeq, Sep 2010]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.28T>G (p.F10V) alteration is located in exon 2 (coding exon 2) of the TBC1D17 gene. This alteration results from a T to G substitution at nucleotide position 28, causing the phenylalanine (F) at amino acid position 10 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
