Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2024The c.1018C>A (p.L340I) alteration is located in exon 8 (coding exon 7) of the LRRC31 gene. This alteration results from a C to A substitution at nucleotide position 1018, causing the leucine (L) at amino acid position 340 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
