The c.550T>C (p.F184L) alteration is located in exon 4 (coding exon 4) of the ZNF773 gene. This alteration results from a T to C substitution at nucleotide position 550, causing the phenylalanine (F) at amino acid position 184 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
