Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.544C>T (p.L182F) alteration is located in exon 1 (coding exon 1) of the KLHDC7B gene. This alteration results from a C to T substitution at nucleotide position 544, causing the leucine (L) at amino acid position 182 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
