Genes affected
LCK (HGNC:6524): (LCK proto-oncogene, Src family tyrosine kinase) This gene is a member of the Src family of protein tyrosine kinases (PTKs). The encoded protein is a key signaling molecule in the selection and maturation of developing T-cells. It contains N-terminal sites for myristylation and palmitylation, a PTK domain, and SH2 and SH3 domains which are involved in mediating protein-protein interactions with phosphotyrosine-containing and proline-rich motifs, respectively. The protein localizes to the plasma membrane and pericentrosomal vesicles, and binds to cell surface receptors, including CD4 and CD8, and other signaling molecules. Multiple alternatively spliced variants encoding different isoforms have been described. [provided by RefSeq, Aug 2016]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -15 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.54).
BP6
Variant 1-32276710-A-G is Benign according to our data. Variant chr1-32276710-A-G is described in ClinVar as [Benign]. Clinvar id is 541835.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=1.2 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00637 (970/152280) while in subpopulation AFR AF= 0.0227 (942/41554). AF 95% confidence interval is 0.0215. There are 10 homozygotes in gnomad4. There are 461 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 10 AR gene
