Genes affected
RAD21L1 (HGNC:16271): (RAD21 cohesin complex component like 1) Predicted to enable chromatin binding activity. Predicted to be involved in mitotic sister chromatid cohesion; replication-born double-strand break repair via sister chromatid exchange; and synaptonemal complex assembly. Predicted to act upstream of or within several processes, including double-strand break repair via homologous recombination; homologous chromosome segregation; and seminiferous tubule development. Predicted to be located in lateral element. Predicted to be part of nuclear meiotic cohesin complex and nuclear mitotic cohesin complex. Predicted to be active in synaptonemal complex.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 14, 2023The c.689T>A (p.M230K) alteration is located in exon 7 (coding exon 6) of the RAD21L1 gene. This alteration results from a T to A substitution at nucleotide position 689, causing the methionine (M) at amino acid position 230 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
