Genes affected
DHX40 (HGNC:18018): (DEAH-box helicase 40) This gene encodes a member of the DExH/D box family of ATP-dependent RNA helicases that have an essential role in RNA metabolism. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 17.[provided by RefSeq, Oct 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.926C>T (p.T309I) alteration is located in exon 7 (coding exon 7) of the DHX40 gene. This alteration results from a C to T substitution at nucleotide position 926, causing the threonine (T) at amino acid position 309 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
