Genes affected

LMO1 (HGNC:6641): (LIM domain only 1) This locus encodes a transcriptional regulator that contains two cysteine-rich LIM domains but lacks a DNA-binding domain. LIM domains may play a role in protein interactions; thus the encoded protein may regulate transcription by competitively binding to specific DNA-binding transcription factors. Alterations at this locus have been associated with acute lymphoblastic T-cell leukemia. Chromosomal rearrangements have been observed between this locus and at least two loci, the delta subunit of the T-cell antigen receptor gene and the LIM domain binding 1 gene. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2012]

Aug 10, 2023

The c.118T>G (p.L40V) alteration is located in exon 2 (coding exon 2) of the LMO1 gene. This alteration results from a T to G substitution at nucleotide position 118, causing the leucine (L) at amino acid position 40 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
