The c.833C>A (p.T278N) alteration is located in exon 7 (coding exon 7) of the PALMD gene. This alteration results from a C to A substitution at nucleotide position 833, causing the threonine (T) at amino acid position 278 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
