Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.1030G>A (p.D344N) alteration is located in exon 8 (coding exon 7) of the LRRC31 gene. This alteration results from a G to A substitution at nucleotide position 1030, causing the aspartic acid (D) at amino acid position 344 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
