Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.388G>A (p.A130T) alteration is located in exon 2 (coding exon 1) of the PSD4 gene. This alteration results from a G to A substitution at nucleotide position 388, causing the alanine (A) at amino acid position 130 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
