Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 10, 2023The c.286C>T (p.R96C) alteration is located in exon 3 (coding exon 3) of the PSMA8 gene. This alteration results from a C to T substitution at nucleotide position 286, causing the arginine (R) at amino acid position 96 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
