Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.450C>G (p.F150L) alteration is located in exon 4 (coding exon 4) of the SMC5 gene. This alteration results from a C to G substitution at nucleotide position 450, causing the phenylalanine (F) at amino acid position 150 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
