The c.1151C>T (p.T384M) 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 1151, causing the threonine (T) at amino acid position 384 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
