Genes affected

SOX6 (HGNC:16421): (SRY-box transcription factor 6) This gene encodes a member of the D subfamily of sex determining region y-related transcription factors that are characterized by a conserved DNA-binding domain termed the high mobility group box and by their ability to bind the minor groove of DNA. The encoded protein is a transcriptional activator that is required for normal development of the central nervous system, chondrogenesis and maintenance of cardiac and skeletal muscle cells. The encoded protein interacts with other family members to cooperatively activate gene expression. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SOX6. . Gene score misZ 1.9285 (greater than the threshold 3.09). Trascript score misZ 3.2843 (greater than threshold 3.09). GenCC has associacion of gene with Tolchin-Le Caignec syndrome.

The c.2246C>G (p.P749R) alteration is located in exon 16 (coding exon 15) of the SOX6 gene. This alteration results from a C to G substitution at nucleotide position 2246, causing the proline (P) at amino acid position 749 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
