Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.997G>T (p.A333S) alteration is located in exon 7 (coding exon 7) of the TIMD4 gene. This alteration results from a G to T substitution at nucleotide position 997, causing the alanine (A) at amino acid position 333 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
