Genes affected

RSPRY1 (HGNC:29420): (ring finger and SPRY domain containing 1) This gene encodes a glycoprotein that contains a RING-type zinc finger domain and an SPRY domain of unknown function. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2015]

RSPRY1 Gene-Disease associations (from GenCC):

• progressive spondyloepimetaphyseal dysplasia-short stature-short fourth metatarsals-intellectual disability syndrome

  Inheritance: AR Classification: STRONG, MODERATE, SUPPORTIVE Submitted by: G2P, Labcorp Genetics (formerly Invitae), Ambry Genetics, Orphanet
