Genetic Variant ASB12:p.Arg219His (chrX-64224995-C-T) – ACMG Classification: Likely_benign (-6 pts)

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_130388.4(ASB12):c.656G>A(p.Arg219His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000474 in 1,203,311 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 18 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 Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R219C) has been classified as Uncertain significance.

Genes affected

ASB12 (HGNC:19763): (ankyrin repeat and SOCS box containing 12) The protein encoded by this gene is a member of the ankyrin repeat and SOCS box-containing (ASB) family of proteins. They contain ankyrin repeat sequence and a SOCS box domain. The SOCS box serves to couple suppressor of cytokine signalling (SOCS) proteins and their binding partners with the elongin B and C complex, possibly targeting them for degradation.

The c.656G>A (p.R219H) alteration is located in exon 2 (coding exon 1) of the ASB12 gene. This alteration results from a G to A substitution at nucleotide position 656, causing the arginine (R) at amino acid position 219 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
