Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 1P and 6B. PP2BP4BP6BS2

The NM_001037333.3(CYFIP2):c.8C>T(p.Thr3Met) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000894 in 1,566,304 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. T3T) has been classified as Likely benign.

Genes affected

CYFIP2 (HGNC:13760): (cytoplasmic FMR1 interacting protein 2) Predicted to enable small GTPase binding activity. Involved in activation of cysteine-type endopeptidase activity; apoptotic process; and cell-cell adhesion. Located in perinuclear region of cytoplasm and synapse. Part of SCAR complex. Implicated in developmental and epileptic encephalopathy 65. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2

Missense variant in the CYFIP2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 20 curated pathogenic missense variants (we use a threshold of 10). The gene has 46 curated benign missense variants. Gene score misZ: 6.0129 (above the threshold of 3.09). Trascript score misZ: 6.9267 (above the threshold of 3.09). GenCC associations: The gene is linked to developmental and epileptic encephalopathy, 65, developmental and epileptic encephalopathy, 76, undetermined early-onset epileptic encephalopathy.

BP4

Computational evidence support a benign effect (MetaRNN=0.37277308).

BP6

Variant 5-157285369-C-T is Benign according to our data. Variant chr5-157285369-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 2440664.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.

BS2

High AC in GnomAdExome4 at 13 AD gene.
