Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 31, 2023The c.757A>C (p.K253Q) alteration is located in exon 4 (coding exon 4) of the TIMD4 gene. This alteration results from a A to C substitution at nucleotide position 757, causing the lysine (K) at amino acid position 253 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
