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.

Ambry Genetics

Aug 10, 2023

The c.683A>G (p.Y228C) alteration is located in exon 5 (coding exon 5) of the FAM188B gene. This alteration results from a A to G substitution at nucleotide position 683, causing the tyrosine (Y) at amino acid position 228 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
