Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2024The c.674T>C (p.I225T) alteration is located in exon 7 (coding exon 7) of the LRRC34 gene. This alteration results from a T to C substitution at nucleotide position 674, causing the isoleucine (I) at amino acid position 225 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
