Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 14, 2024The c.757G>C (p.V253L) alteration is located in exon 3 (coding exon 3) of the LARP6 gene. This alteration results from a G to C substitution at nucleotide position 757, causing the valine (V) at amino acid position 253 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
