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]

Feb 21, 2024

The c.53C>A (p.P18Q) alteration is located in exon 1 (coding exon 1) of the LIMCH1 gene. This alteration results from a C to A substitution at nucleotide position 53, causing the proline (P) at amino acid position 18 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
