Genes affected

DMRTC2 (HGNC:13911): (DMRT like family C2) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in germ cell development; regulation of transcription by RNA polymerase II; and sex differentiation. Predicted to act upstream of or within male gamete generation and positive regulation of histone H3-K9 methylation. Predicted to be located in XY body. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.72).
• BP7: Synonymous conserved (PhyloP=0.539 with no splicing effect.
