Arina Puzriakova (Genomics England Curator)

Comment on list classification: Multiple individuals with KCNMA1-related channelopathy characterised by a variety of neurologic symptoms, with both mono- and biallelic cases reported. Only a single patient described by Liang et al., 2019 (PMID: 31152168) with hearing impairment and therefore a Red rating on this panel is appropriate.
