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.154A>G (p.I52V) alteration is located in exon 2 (coding exon 2) of the LIMCH1 gene. This alteration results from a A to G substitution at nucleotide position 154, causing the isoleucine (I) at amino acid position 52 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
