Genes affected

PMF1 (HGNC:9112): (polyamine modulated factor 1) Enables leucine zipper domain binding activity and transcription coactivator activity. Involved in chromosome segregation. Located in Golgi apparatus; kinetochore; and nucleoplasm. Part of MIS12/MIND type complex. Implicated in bladder carcinoma and urinary bladder cancer. [provided by Alliance of Genome Resources, Apr 2022]

PMF1 links:

PMF1-BGLAP (HGNC:42953): (PMF1-BGLAP readthrough) This locus represents naturally occurring read-through transcription between the neighboring PMF1 (polyamine-modulated factor 1) and BGLAP (bone gamma-carboxyglutamate Gla protein) genes on chromosome 1. Alternative splicing results in multiple transcript variants encoding isoforms that share sequence identity with the upstream gene product, but they contain distinct C-termini due to frameshifts versus the downstream gene coding sequence.

The c.142A>C (p.K48Q) alteration is located in exon 1 (coding exon 1) of the PMF1-BGLAP gene. This alteration results from a A to C substitution at nucleotide position 142, causing the lysine (K) at amino acid position 48 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
