Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_001136200.2(BORCS7):​c.80C>A​(p.Thr27Asn) variant causes a missense change. The variant allele was found at a frequency of 0.000000701 in 1,426,560 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T27I) has been classified as Uncertain significance.

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]
