Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.203A>G (p.D68G) alteration is located in exon 2 (coding exon 2) of the PSMA8 gene. This alteration results from a A to G substitution at nucleotide position 203, causing the aspartic acid (D) at amino acid position 68 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
