Genes affected

ISCA1 (HGNC:28660): (iron-sulfur cluster assembly 1) ISCA1 is a mitochondrial protein involved in the biogenesis and assembly of iron-sulfur clusters, which play a role in electron-transfer reactions (Cozar-Castellano et al., 2004 [PubMed 15262227]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.
