Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.223C>T (p.R75C) alteration is located in exon 2 (coding exon 1) of the LCE2A gene. This alteration results from a C to T substitution at nucleotide position 223, causing the arginine (R) at amino acid position 75 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
