Genes affected

DISC1 (HGNC:2888): (DISC1 scaffold protein) This gene encodes a protein with multiple coiled coil motifs which is located in the nucleus, cytoplasm and mitochondria. The protein is involved in neurite outgrowth and cortical development through its interaction with other proteins. This gene is disrupted in a t(1;11)(q42.1;q14.3) translocation which segregates with schizophrenia and related psychiatric disorders in a large Scottish family. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

The c.161T>G (p.I54S) alteration is located in exon 2 (coding exon 2) of the DISC1 gene. This alteration results from a T to G substitution at nucleotide position 161, causing the isoleucine (I) at amino acid position 54 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
