Genes affected
MMS22L (HGNC:21475): (MMS22 like, DNA repair protein) The protein encoded by this gene forms a complex with tonsoku-like, DNA repair protein (TONSL), and this complex recognizes and repairs DNA double-strand breaks at sites of stalled or collapsed replication forks. The encoded protein also can bind with the histone-associated protein NFKBIL2 to help regulate the chromatin state at stalled replication forks. Finally, this gene appears to be overexpressed in most lung and esophageal cancers. Multiple transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.2411C>T (p.S804L) alteration is located in exon 17 (coding exon 16) of the MMS22L gene. This alteration results from a C to T substitution at nucleotide position 2411, causing the serine (S) at amino acid position 804 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
