Genes affected

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

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]

ENSG00000282772 (HGNC:):

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=0.13305357).

The c.80C>T (p.T27I) 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 80, causing the threonine (T) at amino acid position 27 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
