Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.886C>T (p.R296W) alteration is located in exon 7 (coding exon 7) of the PGS1 gene. This alteration results from a C to T substitution at nucleotide position 886, causing the arginine (R) at amino acid position 296 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
