Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2022The c.94C>A (p.L32I) alteration is located in exon 2 (coding exon 2) of the LRRC3C gene. This alteration results from a C to A substitution at nucleotide position 94, causing the leucine (L) at amino acid position 32 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
