The c.566C>T (p.A189V) alteration is located in exon 6 (coding exon 5) of the FAM114A2 gene. This alteration results from a C to T substitution at nucleotide position 566, causing the alanine (A) at amino acid position 189 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
