The c.322C>G (p.Q108E) alteration is located in exon 6 (coding exon 4) of the SAMD7 gene. This alteration results from a C to G substitution at nucleotide position 322, causing the glutamine (Q) at amino acid position 108 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
