Genes affected

SYNDIG1 (HGNC:15885): (synapse differentiation inducing 1) This gene encodes a protein that belongs to the interferon-induced transmembrane family of proteins. A similar protein in rat is thought to regulate the development of excitatory synapses. [provided by RefSeq, Jul 2013]

Ambry Genetics

Dec 13, 2022

The c.637A>C (p.K213Q) alteration is located in exon 4 (coding exon 3) of the SYNDIG1 gene. This alteration results from a A to C substitution at nucleotide position 637, causing the lysine (K) at amino acid position 213 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
