2-182934796-T-C

Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 1P and 10B. PP2BP4_StrongBP6_ModerateBS2

The NM_013436.5(NCKAP1):ā€‹c.2815A>Gā€‹(p.Ile939Val) variant causes a missense change. The variant allele was found at a frequency of 0.000122 in 1,487,136 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I939N) has been classified as Uncertain significance.

Genes affected
NCKAP1 (HGNC:7666): (NCK associated protein 1) Contributes to small GTPase binding activity. Involved in Rac protein signal transduction; positive regulation of Arp2/3 complex-mediated actin nucleation; and positive regulation of lamellipodium assembly. Located in extracellular exosome and focal adhesion. Part of SCAR complex. [provided by Alliance of Genome Resources, Apr 2022]
