Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 17, 2023The c.4G>A (p.A2T) alteration is located in exon 1 (coding exon 1) of the PGS1 gene. This alteration results from a G to A substitution at nucleotide position 4, causing the alanine (A) at amino acid position 2 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
