The c.554T>C (p.V185A) alteration is located in exon 6 (coding exon 4) of the ZNF385B gene. This alteration results from a T to C substitution at nucleotide position 554, causing the valine (V) at amino acid position 185 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
