Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001384743.1(AMZ1):c.57C>A(p.Asp19Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,184 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D19V) has been classified as Uncertain significance.

The c.57C>A (p.D19E) alteration is located in exon 2 (coding exon 1) of the AMZ1 gene. This alteration results from a C to A substitution at nucleotide position 57, causing the aspartic acid (D) at amino acid position 19 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
