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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.067745805 fraction of the gene. Cryptic splice site detected, with MaxEntScore 2.6, offset of 9, new splice context is: atgttgattaattgaaccAGata. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

BS2

High AC in GnomAd4 at 7 AD gene.
