The c.1040C>T (p.P347L) alteration is located in exon 8 (coding exon 8) of the PDZD4 gene. This alteration results from a C to T substitution at nucleotide position 1040, causing the proline (P) at amino acid position 347 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
