Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.860T>C (p.L287P) alteration is located in exon 2 (coding exon 1) of the PSD4 gene. This alteration results from a T to C substitution at nucleotide position 860, causing the leucine (L) at amino acid position 287 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
