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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP3

Multiple lines of computational evidence support a deleterious effect 6: AlphaMissense, BayesDel_addAF, Cadd, Eigen, FATHMM_MKL, PROVEAN [when max_spliceai, M_CAP, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.31559873).

The c.884G>T (p.R295L) alteration is located in exon 8 (coding exon 8) of the LIMCH1 gene. This alteration results from a G to T substitution at nucleotide position 884, causing the arginine (R) at amino acid position 295 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
