Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.776T>G (p.L259W) alteration is located in exon 6 (coding exon 6) of the PSMG1 gene. This alteration results from a T to G substitution at nucleotide position 776, causing the leucine (L) at amino acid position 259 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
