Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.2606C>G (p.T869S) alteration is located in exon 13 (coding exon 13) of the PSD3 gene. This alteration results from a C to G substitution at nucleotide position 2606, causing the threonine (T) at amino acid position 869 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
