The c.322G>A (p.A108T) alteration is located in exon 4 (coding exon 3) of the CCDC190 gene. This alteration results from a G to A substitution at nucleotide position 322, causing the alanine (A) at amino acid position 108 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
