Genes affected

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.425C>G (p.P142R) alteration is located in exon 3 (coding exon 2) of the AKT1S1 gene. This alteration results from a C to G substitution at nucleotide position 425, causing the proline (P) at amino acid position 142 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
