Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.1872G>T (p.K624N) alteration is located in exon 2 (coding exon 2) of the LRFN1 gene. This alteration results from a G to T substitution at nucleotide position 1872, causing the lysine (K) at amino acid position 624 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
