Genes affected
HLTF (HGNC:11099): (helicase like transcription factor) This gene encodes a member of the SWI/SNF family. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein contains a RING finger DNA binding motif. Two transcript variants encoding the same protein have been found for this gene. However, use of an alternative translation start site produces an isoform that is truncated at the N-terminus compared to the full-length protein. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2023The c.2983A>T (p.M995L) alteration is located in exon 25 (coding exon 25) of the HLTF gene. This alteration results from a A to T substitution at nucleotide position 2983, causing the methionine (M) at amino acid position 995 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
