Genes affected

BLOC1S5 (HGNC:18561): (biogenesis of lysosomal organelles complex 1 subunit 5) This gene encodes a component of BLOC-1 (biogenesis of lysosome-related organelles complex 1). Components of this complex are involved in the biogenesis of organelles such as melanosomes and platelet-dense granules. A mouse model for Hermansky-Pudlak Syndrome is mutated in the murine version of this gene. Alternative splicing results in multiple transcript variants. Read-through transcription exists between this gene and the upstream EEF1E1 (eukaryotic translation elongation factor 1 epsilon 1) gene, as well as with the downstream TXNDC5 (thioredoxin domain containing 5) gene.

EEF1E1-BLOC1S5 (HGNC:49187): (EEF1E1-BLOC1S5 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring EEF1E1 (eukaryotic translation elongation factor 1 epsilon 1) and MUTED (muted homolog) genes on chromosome 6. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD) and is unlikely to produce a protein product. [provided by RefSeq, Dec 2010]

BLOC1S5-TXNDC5 (HGNC:42001): (BLOC1S5-TXNDC5 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring MUTED (muted homolog) and TXNDC5 (thioredoxin domain containing 5) genes on chromosome 6. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD) and is unlikely to produce a protein product. [provided by RefSeq, Dec 2010]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.441 is higher than 0.05.
