Genes affected
RBM45 (HGNC:24468): (RNA binding motif protein 45) This gene encodes a member of the RNA recognition motif (RRM)-type RNA-binding family of proteins. This protein exhibits preferential binding to poly(C) RNA. Initial cloning of this gene found that the rat ortholog was dynamically expressed in the developing rat brain. This protein has been localized to inclusion bodies in the brain and spinal cord of amyotrophic lateral sclerosis and Alzheimer's patients. A pseudogene has been identified on chromosome 8.

The c.944T>C (p.I315T) alteration is located in exon 6 (coding exon 6) of the RBM45 gene. This alteration results from a T to C substitution at nucleotide position 944, causing the isoleucine (I) at amino acid position 315 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
