Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.242C>T (p.P81L) alteration is located in exon 3 (coding exon 3) of the LSMEM2 gene. This alteration results from a C to T substitution at nucleotide position 242, causing the proline (P) at amino acid position 81 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
