Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_004304.5(ALK):c.3004C>T(p.His1002Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000434 in 1,614,102 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H1002P) has been classified as Uncertain significance.

Neuroblastoma, susceptibility to, 3 Uncertain:1
In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 1002 of the ALK protein (p.His1002Tyr). This variant is present in population databases (rs764036965, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with ALK-related conditions. ClinVar contains an entry for this variant (Variation ID: 581241). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.H1002Y variant (also known as c.3004C>T), located in coding exon 18 of the ALK gene, results from a C to T substitution at nucleotide position 3004. The histidine at codon 1002 is replaced by tyrosine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
