Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.2278C>T (p.P760S) alteration is located in exon 5 (coding exon 5) of the PDZD8 gene. This alteration results from a C to T substitution at nucleotide position 2278, causing the proline (P) at amino acid position 760 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
