Genetic Variant AADACL3:p.Arg216Trp (chr1-12725418-C-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001103170.3(AADACL3):c.646C>T(p.Arg216Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,613,850 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/18 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. R216Q) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.475C>T (p.R159W) alteration is located in exon 4 (coding exon 3) of the AADACL3 gene. This alteration results from a C to T substitution at nucleotide position 475, causing the arginine (R) at amino acid position 159 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
