Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.1649G>A (p.G550E) alteration is located in exon 10 (coding exon 9) of the LRRC31 gene. This alteration results from a G to A substitution at nucleotide position 1649, causing the glycine (G) at amino acid position 550 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
