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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2024The c.1316T>C (p.I439T) alteration is located in exon 12 (coding exon 12) of the ST7L gene. This alteration results from a T to C substitution at nucleotide position 1316, causing the isoleucine (I) at amino acid position 439 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
