Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 16, 2024The c.926T>C (p.L309S) alteration is located in exon 7 (coding exon 6) of the EFCAB7 gene. This alteration results from a T to C substitution at nucleotide position 926, causing the leucine (L) at amino acid position 309 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
