The c.1020C>A (p.H340Q) alteration is located in exon 11 (coding exon 11) of the SIDT2 gene. This alteration results from a C to A substitution at nucleotide position 1020, causing the histidine (H) at amino acid position 340 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
