Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 05, 2021The c.782G>C (p.R261T) alteration is located in exon 9 (coding exon 9) of the SP140L gene. This alteration results from a G to C substitution at nucleotide position 782, causing the arginine (R) at amino acid position 261 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
