Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.803C>T (p.A268V) alteration is located in exon 6 (coding exon 6) of the PGS1 gene. This alteration results from a C to T substitution at nucleotide position 803, causing the alanine (A) at amino acid position 268 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
