The c.328G>A (p.A110T) alteration is located in exon 4 (coding exon 2) of the C1QTNF8 gene. This alteration results from a G to A substitution at nucleotide position 328, causing the alanine (A) at amino acid position 110 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
