Genes affected

ISM1 (HGNC:16213): (isthmin 1) Predicted to be involved in negative regulation of angiogenesis. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

TASP1 (HGNC:15859): (taspase 1) This gene encodes an endopeptidase that cleaves specific substrates following aspartate residues. The encoded protein undergoes posttranslational autoproteolytic processing to generate alpha and beta subunits, which reassemble into the active alpha2-beta2 heterotetramer. It is required to cleave MLL, a protein required for the maintenance of HOX gene expression, and TFIIA, a basal transcription factor. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

TASP1 Gene-Disease associations (from GenCC):

• Suleiman-El-Hattab syndrome

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: G2P, Ambry Genetics, Labcorp Genetics (formerly Invitae), PanelApp Australia

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.
