Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.1630A>C (p.I544L) alteration is located in exon 10 (coding exon 9) of the LRRC31 gene. This alteration results from a A to C substitution at nucleotide position 1630, causing the isoleucine (I) at amino acid position 544 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
