Genes affected

ST7L (HGNC:18441): (suppression of tumorigenicity 7 like) This gene was identified by its similarity to the ST7 tumor suppressor gene found in the chromosome 7q31 region. This gene is clustered in a tail-to-tail manner with the WNT2B gene in a chromosomal region known to be deleted and rearranged in a variety of cancers. Several transcript variants encoding many different isoforms have been described, but some have not been fully characterized. [provided by RefSeq, Feb 2011]

Apr 23, 2024

The c.953A>G (p.D318G) alteration is located in exon 8 (coding exon 8) of the ST7L gene. This alteration results from a A to G substitution at nucleotide position 953, causing the aspartic acid (D) at amino acid position 318 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
