Description of a novel patient with the TRPM3 recurrent p.Val837Met variant.

Abstract excerpt

De novo heterozygous missense mutations in TRPM3 have been shown to cause developmental and epileptic encephalopathies (DEE). It is a very rare condition, as only 9 patients have been described to date. We report here a novel patient carrying the recurrent p.Val837Met variant and presenting new clinical features, such as trigonocephaly, expanding the phenotypical spectrum of the disease.
