Genes affected
ALK (HGNC:427): (ALK receptor tyrosine kinase) This gene encodes a receptor tyrosine kinase, which belongs to the insulin receptor superfamily. This protein comprises an extracellular domain, an hydrophobic stretch corresponding to a single pass transmembrane region, and an intracellular kinase domain. It plays an important role in the development of the brain and exerts its effects on specific neurons in the nervous system. This gene has been found to be rearranged, mutated, or amplified in a series of tumours including anaplastic large cell lymphomas, neuroblastoma, and non-small cell lung cancer. The chromosomal rearrangements are the most common genetic alterations in this gene, which result in creation of multiple fusion genes in tumourigenesis, including ALK (chromosome 2)/EML4 (chromosome 2), ALK/RANBP2 (chromosome 2), ALK/ATIC (chromosome 2), ALK/TFG (chromosome 3), ALK/NPM1 (chromosome 5), ALK/SQSTM1 (chromosome 5), ALK/KIF5B (chromosome 10), ALK/CLTC (chromosome 17), ALK/TPM4 (chromosome 19), and ALK/MSN (chromosome X).[provided by RefSeq, Jan 2011]
CLIP4 (HGNC:26108): (CAP-Gly domain containing linker protein family member 4) Predicted to enable microtubule plus-end binding activity. Predicted to be involved in cytoplasmic microtubule organization. Located in intracellular membrane-bounded organelle. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

PM4
Nonframeshift variant in NON repetitive region in NM_004304.5. Strenght limited to Supporting due to length of the change: 1aa.
BP6
Variant 2-29193511-CCTT-C is Benign according to our data. Variant chr2-29193511-CCTT-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 239839.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000276 (42/152142) while in subpopulation AMR AF = 0.00157 (24/15270). AF 95% confidence interval is 0.00108. There are 0 homozygotes in GnomAd4. There are 25 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 42 AD gene.
