Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 29, 2023The c.863C>G (p.P288R) alteration is located in exon 4 (coding exon 4) of the SHISA8 gene. This alteration results from a C to G substitution at nucleotide position 863, causing the proline (P) at amino acid position 288 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
