Feb 17, 2024

The c.791C>T (p.T264M) alteration is located in exon 6 (coding exon 6) of the PNPLA5 gene. This alteration results from a C to T substitution at nucleotide position 791, causing the threonine (T) at amino acid position 264 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
