Genes affected

CABLES1 (HGNC:25097): (Cdk5 and Abl enzyme substrate 1) This gene encodes a protein involved in regulation of the cell cycle through interactions with several cyclin-dependent kinases. One study (PMID: 16177568) reported aberrant splicing of transcripts from this gene which results in removal of the cyclin binding domain only in human cancer cells, and reduction in gene expression was shown in colorectal cancers (PMID: 17982127).Multiple transcript variants encoding different isoforms have been found for this gene.

TMEM241 (HGNC:31723): (transmembrane protein 241) Predicted to enable antiporter activity. Predicted to be involved in carbohydrate transport and transmembrane transport. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.15354446).

Collection Method: clinical testing

The c.1350C>G (p.D450E) alteration is located in exon 7 (coding exon 7) of the CABLES1 gene. This alteration results from a C to G substitution at nucleotide position 1350, causing the aspartic acid (D) at amino acid position 450 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
