The c.279C>G (p.H93Q) alteration is located in exon 2 (coding exon 1) of the RNASE6 gene. This alteration results from a C to G substitution at nucleotide position 279, causing the histidine (H) at amino acid position 93 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
