Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2023The c.934C>T (p.R312W) alteration is located in exon 7 (coding exon 7) of the LRRC40 gene. This alteration results from a C to T substitution at nucleotide position 934, causing the arginine (R) at amino acid position 312 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
