Genes affected

LRRCC1 (HGNC:29373): (leucine rich repeat and coiled-coil centrosomal protein 1) This gene encodes a centrosomal protein that maintains the structural integrity of the centrosome and plays a key role in mitotic spindle formation. The encoded protein contains an N-terminal leucine-rich repeat domain and a C-terminal coiled-coil domain. It associates with the centrosome throughout the cell cycle and accumulates on the mitotic centrosome. [provided by RefSeq, Mar 2017]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.78

Feb 17, 2022

The c.245G>A (p.G82E) alteration is located in exon 2 (coding exon 2) of the LRRCC1 gene. This alteration results from a G to A substitution at nucleotide position 245, causing the glycine (G) at amino acid position 82 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
