Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2024The c.241C>T (p.R81W) alteration is located in exon 3 (coding exon 3) of the SP140L gene. This alteration results from a C to T substitution at nucleotide position 241, causing the arginine (R) at amino acid position 81 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
