Genes affected

LIMCH1 (HGNC:29191): (LIM and calponin homology domains 1) Enables myosin II head/neck binding activity. Involved in several processes, including cytoplasmic actin-based contraction involved in cell motility; positive regulation of stress fiber assembly; and regulation of focal adhesion assembly. Located in stress fiber. Colocalizes with myosin II complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.1300C>T (p.R434W) alteration is located in exon 12 (coding exon 12) of the LIMCH1 gene. This alteration results from a C to T substitution at nucleotide position 1300, causing the arginine (R) at amino acid position 434 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
