Genes affected
HCK (HGNC:4840): (HCK proto-oncogene, Src family tyrosine kinase) The protein encoded by this gene is a member of the Src family of tyrosine kinases. This protein is primarily hemopoietic, particularly in cells of the myeloid and B-lymphoid lineages. It may help couple the Fc receptor to the activation of the respiratory burst. In addition, it may play a role in neutrophil migration and in the degranulation of neutrophils. Multiple isoforms with different subcellular distributions are produced due to both alternative splicing and the use of alternative translation initiation codons, including a non-AUG (CUG) codon.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.415C>G (p.L139V) alteration is located in exon 5 (coding exon 5) of the HCK gene. This alteration results from a C to G substitution at nucleotide position 415, causing the leucine (L) at amino acid position 139 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Variant summary: HCK c.415C>G (p.Leu139Val) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00013 in 251372 control chromosomes, predominantly at a frequency of 0.00024 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in HCK causing Autoinflammation with pulmonary and cutaneous vasculitis, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.415C>G in individuals affected with Autoinflammation with pulmonary and cutaneous vasculitis and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 2306892). Based on the evidence outlined above, the variant was classified as uncertain significance. -
