Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.736A>C (p.I246L) alteration is located in exon 7 (coding exon 7) of the LRRC34 gene. This alteration results from a A to C substitution at nucleotide position 736, causing the isoleucine (I) at amino acid position 246 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
