Collection Method: clinical testing

The c.164T>C (p.F55S) alteration is located in exon 2 (coding exon 1) of the AMZ1 gene. This alteration results from a T to C substitution at nucleotide position 164, causing the phenylalanine (F) at amino acid position 55 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
