not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2023The c.497C>A (p.T166K) alteration is located in exon 4 (coding exon 4) of the PGS1 gene. This alteration results from a C to A substitution at nucleotide position 497, causing the threonine (T) at amino acid position 166 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
