Genetic Variant RTL5:p.Ala477Pro (chrX-72130112-C-G) – ACMG Classification: Benign (-8 pts)

Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_001405151.1(RTL5):c.1429G>C(p.Ala477Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000438 in 1,208,690 control chromosomes in the GnomAD database, including 1 homozygotes. There are 20 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 11/17 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. A477T) has been classified as Likely benign.
