The c.2100C>G (p.H700Q) alteration is located in exon 17 (coding exon 17) of the STRN gene. This alteration results from a C to G substitution at nucleotide position 2100, causing the histidine (H) at amino acid position 700 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
