Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2023The c.986T>C (p.I329T) alteration is located in exon 8 (coding exon 8) of the LAP3 gene. This alteration results from a T to C substitution at nucleotide position 986, causing the isoleucine (I) at amino acid position 329 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
