Genes affected

MMS19 (HGNC:13824): (MMS19 homolog, cytosolic iron-sulfur assembly component) Enables estrogen receptor binding activity and transcription coactivator activity. Involved in several processes, including iron-sulfur cluster assembly; positive regulation of nucleobase-containing compound metabolic process; and protein maturation by iron-sulfur cluster transfer. Located in cytosol; nucleoplasm; and spindle. Part of CIA complex and MMXD complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=5.7795955E-7).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.973 is higher than 0.05.
