Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.2489A>C (p.Y830S) alteration is located in exon 13 (coding exon 13) of the PSD3 gene. This alteration results from a A to C substitution at nucleotide position 2489, causing the tyrosine (Y) at amino acid position 830 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
