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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.6T>G (p.D2E) alteration is located in exon 2 (coding exon 1) of the SYNDIG1 gene. This alteration results from a T to G substitution at nucleotide position 6, causing the aspartic acid (D) at amino acid position 2 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
