Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM2 PM5 PP3_Strong

The ENST00000414626.2(LRRCC1):​c.44G>A​(p.Ser15Asn) variant causes a missense change. The variant allele was found at a frequency of 0.00000215 in 1,398,332 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S15T) has been classified as Pathogenic.

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]

E2F5-DT (HGNC:55393): (E2F5 divergent transcript)

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr8-85109594-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 266077.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP3: Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
