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]

Ambry Genetics

Jun 17, 2022

The c.1109G>A (p.R370H) alteration is located in exon 11 (coding exon 11) of the LIMCH1 gene. This alteration results from a G to A substitution at nucleotide position 1109, causing the arginine (R) at amino acid position 370 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
