Genes affected

NCAPD2 (HGNC:24305): (non-SMC condensin I complex subunit D2) Enables histone binding activity. Involved in mitotic chromosome condensation. Located in condensed chromosome; cytosol; and nucleoplasm. Part of condensin complex. Colocalizes with cytoplasm and nuclear chromosome. Implicated in primary autosomal recessive microcephaly. [provided by Alliance of Genome Resources, Apr 2022]

GAPDH-DT (HGNC:55492): (GAPDH divergent transcript)

ACMG classification

Our verdict: Likely_benign. The variant received -5 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP7: Synonymous conserved (PhyloP=0.7 with no splicing effect.
