The c.1319C>T (p.A440V) alteration is located in exon 6 (coding exon 6) of the PALM3 gene. This alteration results from a C to T substitution at nucleotide position 1319, causing the alanine (A) at amino acid position 440 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
