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]

ZC3H14 Gene-Disease associations (from GenCC):

• autosomal recessive non-syndromic intellectual disability

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
• intellectual disability

  Inheritance: AR Classification: LIMITED Submitted by: ClinGen
