Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.658C>A (p.L220I) alteration is located in exon 3 (coding exon 3) of the LARP6 gene. This alteration results from a C to A substitution at nucleotide position 658, causing the leucine (L) at amino acid position 220 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
