Genes affected

ZC3H12B (HGNC:17407): (zinc finger CCCH-type containing 12B) The protein encoded by this gene belongs to a family of CCCH-type zinc finger proteins that are involved in the proinflammatory activation of macrophages. The exact function of this family member is unknown, but it is thought to function as a ribonuclease. [provided by RefSeq, May 2010]

The c.152T>C (p.L51P) alteration is located in exon 1 (coding exon 1) of the ZC3H12B gene. This alteration results from a T to C substitution at nucleotide position 152, causing the leucine (L) at amino acid position 51 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces leucine with proline at codon 51 of the ZC3H12B protein (p.Leu51Pro). The leucine residue is weakly conserved and there is a moderate physicochemical difference between leucine and proline. This variant is present in population databases (rs199856860, ExAC 0.08%). This variant has not been reported in the literature in individuals with ZC3H12B-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. -
