Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 02, 2024The c.203C>A (p.S68Y) alteration is located in exon 2 (coding exon 1) of the PSD4 gene. This alteration results from a C to A substitution at nucleotide position 203, causing the serine (S) at amino acid position 68 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
