Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.490G>A (p.A164T) alteration is located in exon 5 (coding exon 4) of the LRRC20 gene. This alteration results from a G to A substitution at nucleotide position 490, causing the alanine (A) at amino acid position 164 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
