Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.323C>T (p.T108I) alteration is located in exon 3 (coding exon 3) of the PSMG1 gene. This alteration results from a C to T substitution at nucleotide position 323, causing the threonine (T) at amino acid position 108 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
