Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001370299.1(AMIGO2):c.1268C>T(p.Pro423Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000254 in 1,614,076 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. P423S) has been classified as Uncertain significance.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1268C>T (p.P423L) alteration is located in exon 2 (coding exon 1) of the AMIGO2 gene. This alteration results from a C to T substitution at nucleotide position 1268, causing the proline (P) at amino acid position 423 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
