The c.1664T>A (p.M555K) alteration is located in exon 6 (coding exon 6) of the PALM3 gene. This alteration results from a T to A substitution at nucleotide position 1664, causing the methionine (M) at amino acid position 555 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
