Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.579G>T (p.M193I) alteration is located in exon 6 (coding exon 6) of the LMNTD2 gene. This alteration results from a G to T substitution at nucleotide position 579, causing the methionine (M) at amino acid position 193 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
