Genes affected

RNF13 (HGNC:10057): (ring finger protein 13) The protein encoded by this gene contains a RING zinc finger, a motif known to be involved in protein-protein interactions. The specific function of this gene has not yet been determined. Alternatively spliced transcript variants that encode the same protein have been reported. A pseudogene, which is also located on chromosome 3, has been defined for this gene. [provided by RefSeq, Jul 2008]

ANKUB1 (HGNC:29642): (ankyrin repeat and ubiquitin domain containing 1)

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.180006).
• BS2: High AC in GnomAdExome4 at 51 AD gene.

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 13, 2023	This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 19 of the RNF13 protein (p.Leu19Phe). This variant is present in population databases (rs768978970, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with RNF13-related conditions. ClinVar contains an entry for this variant (Variation ID: 1492876). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
