The c.1790T>A (p.V597D) alteration is located in exon 11 (coding exon 11) of the MCTP1 gene. This alteration results from a T to A substitution at nucleotide position 1790, causing the valine (V) at amino acid position 597 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
