Genetic Variant GLYR1:p.Ile235Phe (chr16-4821576-T-A) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_032569.4(GLYR1):c.703A>T(p.Ile235Phe) variant causes a missense change. The variant allele was found at a frequency of 0.00000867 in 1,613,936 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I235V) has been classified as Uncertain significance.
