Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2022The c.1723G>T (p.A575S) alteration is located in exon 18 (coding exon 18) of the ANKRD44 gene. This alteration results from a G to T substitution at nucleotide position 1723, causing the alanine (A) at amino acid position 575 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
