The c.3220G>A (p.V1074M) alteration is located in exon 24 (coding exon 22) of the TECPR1 gene. This alteration results from a G to A substitution at nucleotide position 3220, causing the valine (V) at amino acid position 1074 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
