Genes affected
MNAT1 (HGNC:7181): (MNAT1 component of CDK activating kinase) The protein encoded by this gene, along with cyclin H and CDK7, forms the CDK-activating kinase (CAK) enzymatic complex. This complex activates several cyclin-associated kinases and can also associate with TFIIH to activate transcription by RNA polymerase II. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.386A>G (p.N129S) alteration is located in exon 4 (coding exon 4) of the MNAT1 gene. This alteration results from a A to G substitution at nucleotide position 386, causing the asparagine (N) at amino acid position 129 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
