not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 24, 2024The c.2108G>A (p.R703Q) alteration is located in exon 18 (coding exon 18) of the LRRC7 gene. This alteration results from a G to A substitution at nucleotide position 2108, causing the arginine (R) at amino acid position 703 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
