Genes affected

MAK (HGNC:6816): (male germ cell associated kinase) The product of this gene is a serine/threonine protein kinase related to kinases involved in cell cycle regulation. Studies of the mouse and rat homologs have localized the kinase to the chromosomes during meiosis in spermatogenesis, specifically to the synaptonemal complex that exists while homologous chromosomes are paired. Mutations in this gene have been associated with ciliary defects resulting in retinitis pigmentosa 62. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

TMEM14B (HGNC:21384): (transmembrane protein 14B) Enables identical protein binding activity. Involved in cerebral cortex development; neural precursor cell proliferation; and regulation of G1/S transition of mitotic cell cycle. Predicted to be integral component of membrane. Predicted to be active in mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000272162 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.
