Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 24, 2023The c.4G>T (p.A2S) alteration is located in exon 2 (coding exon 1) of the TCAF1 gene. This alteration results from a G to T substitution at nucleotide position 4, causing the alanine (A) at amino acid position 2 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
