Genes affected

MINDY4 (HGNC:21916): (MINDY lysine 48 deubiquitinase 4) Predicted to enable Lys48-specific deubiquitinase activity. Predicted to be involved in protein K48-linked deubiquitination. [provided by Alliance of Genome Resources, Apr 2022]

MINDY4 links:

INMT-MINDY4 (HGNC:41995): (INMT-MINDY4 readthrough (NMD candidate)) This locus represents rare but naturally occurring read-through transcription between the INMT (indolethylamine N-methyltransferase) and FAM188B (family with sequence similarity 188, member B) genes on chromosome 7. The read-through transcript is unlikely to produce a protein because it is a nonsense-mediated mRNA decay (NMD) candidate based on translation from the supported INMT start codon.

The c.72G>T (p.K24N) alteration is located in exon 2 (coding exon 2) of the FAM188B gene. This alteration results from a G to T substitution at nucleotide position 72, causing the lysine (K) at amino acid position 24 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
