Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS1

The NM_005546.4(ITK):c.631G>C(p.Val211Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000576 in 1,614,148 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). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V211I) has been classified as Uncertain significance.

Genes affected

ITK (HGNC:6171): (IL2 inducible T cell kinase) This gene encodes an intracellular tyrosine kinase expressed in T-cells. The protein contains both SH2 and SH3 domains which are often found in intracellular kinases. It is thought to play a role in T-cell proliferation and differentiation. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.08183372).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000289 (44/152272) while in subpopulation AFR AF = 0.00101 (42/41560). AF 95% confidence interval is 0.000768. There are 0 homozygotes in GnomAd4. There are 23 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
