Genes affected

BORCS7 (HGNC:23516): (BLOC-1 related complex subunit 7) Part of BORC complex. [provided by Alliance of Genome Resources, Apr 2022]

BORCS7 links:

BORCS7-ASMT (HGNC:49183): (BORCS7-ASMT readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring C10orf32 (chromosome 10 open reading frame 32) and AS3MT (arsenic, +3 oxidation state, methyltransferase) genes. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is therefore unlikely to produce a protein product. [provided by RefSeq, Dec 2010]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.17C>T (p.T6M) alteration is located in exon 1 (coding exon 1) of the BORCS7 gene. This alteration results from a C to T substitution at nucleotide position 17, causing the threonine (T) at amino acid position 6 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
