Genes affected

LMO7 (HGNC:6646): (LIM domain 7) This gene encodes a protein containing a calponin homology (CH) domain, a PDZ domain, and a LIM domain, and may be involved in protein-protein interactions. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene, however, the full-length nature of some variants is not known.

Collection Method: clinical testing

The c.233C>A (p.T78K) alteration is located in exon 3 (coding exon 3) of the LMO7 gene. This alteration results from a C to A substitution at nucleotide position 233, causing the threonine (T) at amino acid position 78 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
