Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.593G>A (p.R198Q) alteration is located in exon 7 (coding exon 7) of the LRRC46 gene. This alteration results from a G to A substitution at nucleotide position 593, causing the arginine (R) at amino acid position 198 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
