Genetic Variant RTL5:p.Ser420Arg (chrX-72130283-T-G) – ACMG Classification: Benign (-20 pts)

Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1

The ENST00000609883.3(RTL5):c.1258A>C(p.Ser420Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.108 in 1,197,040 control chromosomes in the GnomAD database, including 7,681 homozygotes. There are 42,413 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 11/16 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S420N) has been classified as Likely benign.
