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

Apr 09, 2024

The c.910C>G (p.P304A) alteration is located in exon 8 (coding exon 8) of the LIMCH1 gene. This alteration results from a C to G substitution at nucleotide position 910, causing the proline (P) at amino acid position 304 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
