Genes affected

DHX37 (HGNC:17210): (DEAH-box helicase 37) This gene encodes a DEAD box protein. DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases. They are implicated in a number of cellular processes involving alteration of RNA secondary structure such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Based on their distribution patterns, some members of this family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. [provided by RefSeq, Jul 2008]

The c.3302G>A (p.R1101H) alteration is located in exon 26 (coding exon 26) of the DHX37 gene. This alteration results from a G to A substitution at nucleotide position 3302, causing the arginine (R) at amino acid position 1101 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
