Genes affected

ZC3H14 (HGNC:20509): (zinc finger CCCH-type containing 14) The protein encoded by this gene is a poly(A)-binding protein that can affect gene expression and poly(A) tail length. The encoded protein may influence mRNA stability, nuclear export, and translation. [provided by RefSeq, May 2016]

Variant summary: ZC3H14 c.37-5C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00019 in 251466 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in ZC3H14 causing Intellectual Disability, Autosomal Recessive 56, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.37-5C>T in individuals affected with Intellectual Disability, Autosomal Recessive 56 and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
