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]

The c.524T>C (p.M175T) alteration is located in exon 3 (coding exon 2) of the SYNDIG1 gene. This alteration results from a T to C substitution at nucleotide position 524, causing the methionine (M) at amino acid position 175 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
